1 Introduction
1.1 What is MET/TEMP II?
MET/TEMP II (formerly Calibrate-it and Generate-it) is temperature sensor
calibration software that interfaces reference thermometers, scanners, and heat
sources to perform typical comparison calibrations of RTDs, thermistors,
thermocouples, and other types of probes and thermometers. The software au-
tomates testing of multiple sensors simultaneously and supports multiple test
instrument configurations.
MET/TEMP II uses thermometer readouts, scanners, dry-wells, baths, and fur-
naces. These instruments can combine to calibrate up to 100 test probes at up to
40 temperature set-points.
MET/TEMP II is available through the Fluke Corporation, Hart Scientific Divi-
sion (Hart). A free demo version of this software is available on our
As we develop new instruments, support for
these instruments will be added to all of our existing software (as applicable)
by way of an upgrade or a Service Release. These upgrades or Service Releases

dows as an Administrator.
When installing MET/TEMP II, setup attempts to locate a previous version of
this software (Calibrate-it) on the computer. MET/TEMP II should be installed
to a different folder than Calibrate-it! During the setup process, any existing
test data is copied to the MET/TEMP II database. Also, any existing configura-
tion files (*.CFG, *.TPC, *.STF, *.STC) from the \CONFIG folder and all re-
port files (*.RPT, *.PGH, *.TXT) from the \REPORTS folder are copied to the
MET/TEMP II \CONFIG and \REPORTS folders respectively.
Important: Before installing MET/TEMP II, make sure the date, time, and
number formats are set according to how you want the dates, times, and
numbers to appear. If test data is being copied from a previous version da-
tabase, all data is formatted according to the current settings when the
data is copied.

Fluke-Direct.com
• DRIVERS.MDB database in the \DATABASE folder
• Any configuration files (*.CFG, *.TPC, *.STC, *.STF, etc.) in the
\CONFIG folder
• Any Report files (*.RPT) in the \REPORTS folder
• Any Paragraph or Notes files (*.PGH, *.TXT) in the \REPORTS folder
• Any other files created by the software since it was installed
The files mentioned above, along with the folders that these files are in, must
be manually deleted using Windows® Explorer to remove them from your
system.
Important: Before deleting the USERDRVR.MDB file, make sure that you
do not need to keep any of the data from tests that have been performed.
Once this file is deleted, all test data is lost!
1.5 Running MET/TEMP II
Important: To use MET/TEMP II, Windows login accounts must be
granted full access to the folder to which the software is installed
(C:\METTEMP2 by default) and all subfolders. If the folders have
read-only access, errors will occur when MET/TEMP II attempts to access
its database and/or configuration files.
Contact your system administrator for assistance in setting up Windows
login accounts with full access to these folders.
Every time this software is run, it checks to make sure that all of the required
.DLL and .VBX files are found on your computer. If the software detects that
9938 MET/TEMP II
User’s Guide

1.888.610.7664 sales@GlobalTestSupply.com
Fluke-Direct.com
an older file has replaced one or more of these files or that the file is not found,
the Shared Files Conflict dialog is displayed detailing the problems found.
Every time you install any software on your computer, it is a good idea to make
a backup of your important files, including all files in the \WINDOWS (or
\WINNT) and \WINDOWS\SYSTEM (or WINNT\SYSTEM) folders. Some-
times during the installation process, a file may be replaced with an older ver-
sion that is not 100% compatible with the first. This may cause the software to
perform unexpectedly or fail to run at all. Replacing a .DLL or .VBX file with a
newer version does not usually cause any problems because these files are typi-
cally backward-compatible. There are, however, exceptions to this rule.
If the Shared Files Conflict dialog is displayed when you run MET/TEMP II, a
list of the files is shown in the Conflicting Files list. Select each of the files, one
at a time, and read the information that appears in the bottom half of the dialog.
Depending on the information given, you must decide what to do. The software
may continue to run without problems, however there is no guarantee of this.
The .DLL and .VBX files are typically located in the \WINDOWS\SYSTEM
(or \WINNT\SYSTEM) folder. If you find it necessary to avoid conflicts, these
files can be copied to the folder where MET/TEMP II was installed. Be sure to
11

compare the files on your computer with the list of required .DLL and .VBX
files.
If the link to the MET/TRACK database is enabled and MET/TEMP II deter-
mines that a compatible version of MET/TRACK is installed on the computer,
the user is prompted to login to the MET/TRACK database. For more details on
configuring MET/TEMP II to link to the MET/TRACK database, refer to Sec-
tion 3.4.9, MET/TRACK Tab.
1.6 Using MET/TEMP II with MET/TRACK
MET/TEMP II is designed to operate as either a “stand-alone” system or it can
be configured to interface with the MET/TRACK database.
When configured to operate as a “stand-alone” system, MET/TEMP II keeps
track of all test equipment and calibration test results in its own database, just
like prior versions (formerly Calibrate-it and Generate-it).
When configured to interface with the MET/TRACK database, MET/TEMP II
still keeps track of all test equipment and calibration test results in its own data-
base, but additionally requires that all instruments being used to perform a cali-
bration as well as all instruments being calibrated have corresponding inventory
records in the MET/TRACK database. For instruments that require calibration,
the MET/TRACK database must also contain up-to-date calibration records.
Also, all calibration test results can be exported to the MET/TRACK database
including probe characterization coefficients and heat source calibration
coefficients.
To configure the operating mode for MET/TEMP II, refer to Section 3.4.9,
MET/TRACK Tab.
Important: Before configuring MET/TEMP II to interface with the
MET/TRACK database, a MET/TEMP II license must be applied to the
MET/TRACK database. A MET/TEMP II license diskette is sold separately
from MET/TEMP II. To apply the license, refer to the MET/TRACK docu-
mentation.
Important: In order to interface with the MET/TRACK database,
MET/TRACK v7.01 or later must be installed! MET/TEMP II does not in-
terface with previous versions of MET/TRACK. Make sure the latest Ser-
vice Pack has been installed. MET/TEMP II will display prompts if it
determines that the installed version of MET/TRACK needs to be up-
graded.
If the link to the MET/TRACK database is enabled, every time MET/TEMP II
starts, the MET/TRACK database login prompt is displayed.

Important: MET/TEMP II requires a MET/TRACK access level of 1 or
higher.
Enter the MET/TRACK user ID and password. If login is successful, a prompt
is displayed indicating the name and access level of the user currently logged
in. If the name of the user does not match the current technician name,
MET/TEMP II asks if you want to update the default technician name. Click

Yes to update the default technician name in MET/TEMP II or click No to pre-
serve the current default technician name.
Once successfully logged into the MET/TRACK database, the MET/TRACK
features are enabled. The MT Asset number box appears on all appropriate
configuration dialogs and all MET/TRACK menu options are enabled.
When configuring a test or opening a configuration file, MET/TEMP II at-
tempts to locate an inventory record in the MET/TRACK database for each
piece of test equipment or probe based on the model, serial number and manu-
facturer. If a match is found, the asset number is read in and displayed in the
MT Asset number box. Otherwise, a prompt is displayed indicating no match-
ing asset record was found. If no asset record exists for this instrument yet,
launch MET/TRACK by clicking Yes and add an inventory record for this in-
strument. If this instrument requires calibration, add a calibration record for
this instrument also. Refer to the MET/TRACK documentation for help on
adding records to the database.
Important: When MET/TEMP II attempts to locate an asset in the
MET/TRACK database, the model, serial number and manufacturer must
match EXACTLY! If an asset record exists but MET/TEMP II is unable to
locate it, you may need to modify the manufacturer information in the
MET/TRACK database.
Depending on the settings on the MET/TRACK tab of the Defaults dialog, the
manufacturer, description, calibration and recalibration dates in MET/TEMP II
can be automatically synchronized with the information in the MET/TRACK
database.
After performing a calibration, the calibration test data can be exported to the
MET/TRACK database. If characterization coefficients need to be calculated
for a probe, this must be done prior to exporting the calibration test data to
MET/TRACK. Calculate the coefficients, then select the Export Calibration
Data to MET/TRACK option in the Utilities menu.

1.7 Required .DLL and .VBX Files
MET/TEMP II requires certain .DLL and .VBX files to function properly. All
required files are shipped on the installation CD. A list of these files and their
required date stamp can be found in the README.TXT file in the folder where
MET/TEMP II is installed.
1.8 Connection of Instruments
Before configuring MET/TEMP II for a test, the test equipment (instruments to
be used) should be connected. MET/TEMP II can be configured to use many
combinations of instruments. The instruments that you use should be deter-
mined by the requirements of the test probes being calibrated and the desired
results. The following is a brief description of the test equipment required by
MET/TEMP II:
Instrument Status Comments
SmartSwitch Required The SmartSwitch is used to connect multiple instruments to a single
COM port on the computer. Use the cable provided.
Reference
Readout
Optional The Reference Readout is typically a thermometer readout with a ref-
erence probe attached. Use a null modem cable (not included).
MET/TEMP II will allow the heat source(s) to be used as the reference.
Scanner Optional The Scanner is the instrument to which all test probes (UUTs) are con-
nected. The Scanner can be the same instrument as the Reference
Readout if it has multiple inputs. Use a null modem cable (not in-
cluded). MET/TEMP II can be configured to not use a scanner if data
needs to be entered manually.
Heat Source(s) Required Up to 4 Heat Sources can be configured. All test probes and the refer-
ence probe must be placed in the same heat source at the same time.
Use a null modem cable (not included). MET/TEMP II can use non-in-
terfaced heat sources. MET/TEMP II also now supports using any
number of Fixed-Point cells as heat sources.
Ambient Condi-
tions Monitoring
Optional MET/TEMP II supports querying ambient temperature and humidity
readings from a Model 1620/5020A ‘DewK’ Thermohygrometer
throughout the testing period.
The example shown in Figure 4 is only for demonstration purposes.

2 Configuring a Test
MET/TEMP II was designed to be very flexible. The user may select from a va-
riety of test equipment and has control over most aspects of a test. Before
MET/TEMP II can perform a test, the software must know the following
information:
• What test equipment is being used?
• How is the test equipment connected?
• What is being calibrated?
• What temperature set-points should be used?
• What scale the readings should be taken in?
The easiest way to create a new configuration is to use the Equipment Info dia-
log. This dialog visually displays the current configuration information and al-
lows access to all of the dialogs necessary to create a configuration. The
Equipment Info dialog is displayed when the Create new configuration option
is selected on the MET/TEMP II Introduction dialog, or by selecting the Equip-
ment Info option in the Configuration menu.
25

Configuring a Test
Figure 8 Equipment Info Dialog
1.888.610.7664 sales@GlobalTestSupply.com
Fluke-Direct.com
The Equipment Info dialog also indicates which configuration items still need
to be completed before a test can be started. All incomplete steps are high-
lighted in red text. When the configuration of a step is complete, the text turns
black.
MET/TEMP II now includes the ability to perform calibrations using
fixed-point cells and also supports calibrating certain heat sources. The follow-
ing sections outline the general configuration process for each of the types of
calibrations that MET/TEMP II supports.
2.1 Comparison, Fixed-Point and Mixed Calibrations
The following section outlines the steps necessary to configure a test to cali-
brate probes using comparison and fixed-point realization.
1. Define the communication settings for the instruments. The communica-
tion settings consist of the COM port to which the SmartSwitch is con-
nected. The SmartSwitch must be connected to an available COM port
on the computer and the baud rate for all instruments must be set to 2400
baud. Refer to Section 4.2.1, Communications Port Configuration, for
details on configuring the communication settings.
2. Define the test equipment to use as the reference. MET/TEMP II requires
a reference. For comparison calibrations, the reference is the standard
against which the test probes are compared. The software must be able to
communicate with the reference readout instrument. The software can
use either a reference readout (thermometer readout) with a reference
probe or it can use the heat source(s) as the reference. Refer to Section
4.3, Reference, for details on configuring the reference readout instru-
ment and the reference probe.
3. Define the test equipment to use as the scanner. The scanner is the instru-
ment to which all of the test probes are connected. To calibrate LIG,
bi-metallic, and other thermometers that cannot be interfaced with a
readout device, or for test probes that are attached to a readout device
that is not supported by MET/TEMP II, the software can be configured
to not use a scanner instrument (the user is prompted to manually enter
all readings at the appropriate times during a test). Refer to Section 4.4,
Scanner, for details on configuring the scanner instrument.
4. Define the instrument(s) to use as heat source(s) for the test. The heat
source(s) are the instruments into which the reference probe and all test
probes are inserted. The software can also be configured to use the heat
source(s) as the reference if desired. Heat sources are used to hold the
temperature of the reference probe and test probes at a constant tempera-
ture so that comparison measurements can be taken. When performing a
calibration using only fixed-points, a special heat source driver needs to
be configured. Refer to Section 4.5, Heat Sources, for details on config-
uring the heat source instrument(s).

5.
Optional - Save the current instrument configuration. Once the above in-
formation has been entered, the current configuration can be saved. The
configuration does not need to be saved to start a test. However, if the
same equipment is going to be used to perform future tests, saving the
configuration provides a quick method to setup the equipment.
6. Define the set-points for the test. The set-points are the temperatures at
which comparison measurements are taken. The software must know the
value and other specifications of each set-point. When using
fixed-points, this is where the fixed-point cell(s) to use are selected. Re-
fer to Section 5.1, Set-points, for details on configuring the set-points.
7.
Optional - Save the current set-point configuration. Once the set-point
information has been entered, the current set-point configuration can be
saved. The set-point configuration does not need to be saved to start a
test. However, if the same set-points are going to be used to perform fu-
ture tests, saving the set-point configuration provides a quick method to
setup the set-points.
8. Define the test probes (UUTs) to calibrate. The software must know the
type of probes, the scale of the readings to take, the channel of the scan-
ner instrument to which each test probe is connected and other informa-
tion. Refer to Section 5.4, Test Probes, for details on configuring the test
probes.
9.
Optional - Save the current test probe configuration. Once the test probe
information has been entered, the current test probe configuration can be
saved. The test probe configuration does not need to be saved to start a
test. However, if the same test probes are going to be calibrated together
in the future, saving the test probe configuration provides a quick
method to setup the test probes.
10. Start the test. The current configuration is checked for missing informa-
tion and/or conflicts and the Test Information dialog is displayed. Fill in
the remaining information for this test and click the OK button to begin.
Refer to Section 5.5, Start Test, for details on the test process.
11. Close the test. When a test is complete it must be closed. Select the Close
Test option in the File menu to close the test.
12. Print the Report of Calibration. To print the Report of Calibration for
each of the test probes, select the Print Report option in the File menu.
Refer to Section 3.6, Print Report, for details on printing a Report of
Calibration.
2.2 Heat Source Calibrations
The following section outlines the steps necessary to configure MET/TEMP II
to calibrate a heat source.
1. Define the communication settings for the instruments. The communica-
tion settings consist of the COM port to which the SmartSwitch is con-
27

Fluke-Direct.com
nected. The SmartSwitch must be connected to an available COM port
on the computer and the baud rate for all instruments must be set to 2400
baud.
2. Configure MET/TEMP II to use the heat source as the reference. When
prompted if you are calibrating a heat source, click Yes. No further con-
figuration is needed for the reference.
3. Define the test equipment to use as the scanner. When performing heat
source calibrations, the scanner will actually act as the reference instru-
ment, with the test probe (UUT) acting as the reference probe.
4. Define the heat source to calibrate. Make sure the Calibrate heat source
check box on the Heat Source Configuration dialog is checked. Fill in
the calibration interval and click the Customer button to indicate the sta-
tus and owner of the heat source. Click the Test Calibration Compatibil-
ity button to make sure MET/TEMP II can calibrate the heat source.
5.
Optional - Save the current instrument configuration. Once the above in-
formation has been entered, the current configuration can be saved. The
configuration does not need to be saved to start a test. However, if the
same equipment is going to be used to perform future tests, saving the
configuration provides a quick method to setup the equipment.
6. Define the set-points for the test. The set-points are the temperatures at
which the heat source will be calibrated (As Found) and the set-points at
which As Left data will be taken. When calibrating a heat source, a
set-point configuration file MUST be opened to define the set-points to
use. Default configuration files are supplied (in degrees C) for all sup-
ported heat sources. Customized configuration files can be created by
opening a default configuration file, changing the settings, and saving the
file under a different name.
7.
Optional - Save the current set-point configuration. Once the set-point
information has been entered, the current set-point configuration can be
saved. The set-point configuration does not need to be saved to start a
test. However, if the same set-points are going to be used to perform fu-
ture tests, saving the set-point configuration provides a quick method to
setup the set-points.
8. Define the test probe to use. MET/TEMP II will actually use the probe
configured as the test probe as a reference probe. The test probe MUST
be configured to read temperature! Fill in the test probe’s calibration and
recalibration dates.
Note: When calibrating a heat source, make sure that the test probe (reference
probe) is calibrated and that the scanner has been configured with the probe’s
calibration coefficients so that the temperature read by the test probe is
accurate!

When the MET/TRACK link is active, the MT Asset number box is displayed.
This box indicates the asset number that is assigned to this fixed-point cell. An
inventory record must exist in the MET/TRACK database for this
fixed-point cell before MET/TEMP II can use it to perform calibrations! If
the calibration and recalibration dates are required, a current calibration
record must also exist in the MET/TRACK database. MET/TEMP II will
automatically attempt to locate the records in the MET/TRACK database when
the model, serial number, and manufacturer information have been entered. If
the asset number is found, MET/TEMP II displays the asset number in the MT
Asset number box. Depending on the settings on the MET/TRACK tab of the
Defaults dialog, the manufacturer, description, and calibration and recalibration
dates may be synchronized with the information in the MET/TRACK database.
If the asset cannot be found in the MET/TRACK database, a message is dis-
played. Click Yes to launch MET/TRACK to create or modify asset records or
clickNotoedittheinformationinMET/TEMPII.
Important: When MET/TEMP II attempts to locate an asset in the
MET/TRACK database, the model, serial number and manufacturer infor-

3.4.7 Test Tab
The Test tab is for selecting defaults specific to the test process.
If the Self-heat test probes (UUTs) before taking readings check box is se-
lected, MET/TEMP II allows the excitation current to run through the test
probe for a period of one minute prior to taking readings. If not selected,
MET/TEMP II bypasses the self-heat step of the test process.
The user is allowed to select the number of measurements to be averaged for
each reading of a test. Once stability is reached at a set-point and the process of
reading each test probe begins, the test probe and the reference probe are sam-
pled the number of times specified here. The test probe readings and reference
probe readings are then averaged to determine the value to be used for the
set-point.
Note: MET/TEMP II uses oversampling, which means that more than the se-
lected number of readings are actually taken. MET/TEMP II then discards the
extra readings and the selected number of readings are averaged to produce the

values printed on the Report of Calibration. This technique is used to eliminate
potentially bad readings.
The Prompt to calculate coefficients when closing test option determines
whether MET/TEMP II should display a prompt when closing a test to launch
the Coefficients and Tables application to calculate characterization coeffi-
cients. This prompt is never displayed after performing heat source
calibrations.
The Take Reference readings in ohms/volts as well as temperature option deter-
mines whether MET/TEMP II should take measurements from the reference
probe in raw units (ohms or volts) in addition to temperature at each set-point
for each UUT. This feature was added for custom reporting purposes and
should usually be left unchecked.
Note: The Take Reference readings in ohms/volts as well as temperature
option may not apply to all reference instruments. Also, this feature does
not apply when using the heat source(s) as the reference. Warning mes-
sages will appear when starting a test if this feature conflicts with the cur-
rent test configuration and/or instruments being used.
The Heat Source Calibration Options settings indicate how MET/TEMP II
should operate when calibrating a heat source.
The Write new coefficients to heat source after calibration indicates whether
the new calculated calibration coefficients for the heat source should be written
to the heat source prior to taking readings at the configured As Left set-points
when performing a heat source calibration. If selected, MET/TEMP II writes
and verifies the new coefficients prior to taking As Left data.
The Set-point Override Options settings indicate what MET/TEMP II should do
if the heat source is unable to achieve the Tolerance setting at a particular
set-point. The user may select between the following options:
• Continue trying until specification is met
• Abort test after time specified below
• Prompt user to override settings after time specified below
• Override settings and continue test after time specified below
The Continue trying until specification is met option is the default. When this
option is selected, MET/TEMP II continually monitors the reference probe
readings until the tolerance specification is met, regardless of how long it takes.
MET/TEMP II does not take readings from the reference probe and UUTs until
this specification is met. Prior to version 3.1 of Calibrate-it, the software be-
haved this way. This option may be recommended when test requirements are
very strict.
The Abort test after time specified below option allows the user to automati-
cally abort a test if the tolerance specification is not met within a specific time
frame. This time frame can be specified using the How much time should the
49

heat source be given? box. The software begins to count down this time ap-
proximately one minute after the heat source set-point is changed. This option
may be recommended when the user is attempting to determine the best set-
tings to use for specific set-points.
The Prompt user to override settings after time specified below option causes
MET/TEMP II to display a message box (which pauses the test until the user
clicks the OK button) prompting the user to override the settings for the current
set-point if the tolerance specification is not met within a specific time frame.
This time frame can be specified using the How much time should the heat
source be given? box. MET/TEMP II begins to count down this time approxi-
mately one minute after the heat source set-point is changed. The user can
override the current set-point settings by selecting the Stability Override option
from the Calibration menu. This option may be recommended when tests are
not left unattended for long periods of time.
The Override settings and continue test after time specified below option causes
MET/TEMP II to ignore the tolerance specification for the current set-point if
not met within a specific time frame and start taking measurements. This time
frame can be specified using the How much time should the heat source be
given? box. MET/TEMP II begins to count down this time approximately one
minute after the heat source set-point is changed. This option may be recom-
mended when tests are left unattended for long periods of time.
The How much time should the heat source be given? box allows the user to
specify the amount of time that must elapse before the action selected above
occurs. The allowable range is from 1 minute to 120 minutes.
Note: This time does not apply if the first option is selected.

ery time MET/TEMP II is launched, it checks to see if MET/TRACK is in-
stalled on the local computer. If so, it makes sure that the version of
MET/TRACK is sufficient for MET/TEMP II to establish the link. If an older
version of MET/TRACK is detected (prior to version 7.0), a message is dis-
played on startup indicating MET/TRACK must be updated to a later version
before the link can be established. This check box should only be checked to

MET/TEMP II has determined that MET/TRACK is or is not installed, this
check box should be unchecked.
If the Enable link to MET/TRACK (always login on startup) check box is
checked, MET/TEMP II will attempt to login to the MET/TRACK database ev-
ery time MET/TEMP II is launched. If not checked, MET/TEMP II operates as
a stand-alone system.
The following settings only apply when the link to the MET/TRACK database
is active:
If the Synchronize calibration and recalibration dates with MET/TRACK check
box is checked, MET/TEMP II will read in the calibration and recalibration
dates (where applicable) for each instrument from the MET/TRACK database
and update the MET/TEMP II database.
If the Synchronize instrument description with MET/TRACK check box is
checked, MET/TEMP II will also read in the description for each instrument
from the MET/TRACK database and update the MET/TEMP II database.
If the Synchronize technician name with MET/TRACK user name check box is
checked, every time a user logs into the MET/TRACK database from
MET/TEMP II, the current MET/TEMP II technician name (as found on the
User tab) is checked against the full name of the MET/TRACK user. If the
names do not match, the Technician name in MET/TEMP II is updated auto-
matically. If this check box is not checked, a prompt is displayed to allow the
user to choose whether or not to synchronize the names.
If the Automatically export calibration data (do not prompt) when closing test
check box is checked, calibration data is automatically exported to the
MET/TRACK database when the Close Test option in the File menu is selected.
If this check box is not checked, a prompt will be displayed to confirm export-
ing calibration data to the MET/TRACK database.
Note: If the user chooses to launch the Coefficients and Tables application to
calculate characterization coefficients when prompted, the calibration data will
NOT be automatically exported to the MET/TRACK database when the test is
closed. Select the Export Calibration Data to MET/TRACK option from the
Utilities menu after all coefficients are calculated to export the calibration data
with the coefficients.
The next few options are used to indicate the setting for the Pass field in the
calibration summary record when calibration data is exported to the
MET/TRACK database.
For temperature vs. temperature data, there are two options:
• Prompt for tolerance and determine Pass field setting automatically
• Always set Pass field to

the tolerance at each set-point for that UUT. The tolerance is then recorded in
the MET/TEMP II database and the Pass field setting is determined based on
whether the calculated error at each set-point falls within the entered tolerance.
If the error at each set-point for a UUT is less than the entered tolerance at that
set-point for that UUT, the Pass field for that UUT is set to “Y”. If the error at
any set-point exceeds the tolerance, the Pass field is set to “N” for that UUT.
If the Always set Pass field to option is selected, the Pass field will always be
set to the selected setting. Use the drop-down list to choose the Pass field
setting.

If the Preview report check box is selected, the report is displayed in the Print
Preview window. If the Preview report check box is not selected, the report is
sent directly to the printer.
If a test is invalid, meaning all of the required data to create a Report of Cali-
bration does not exist in the database, a message is displayed and the report
cannot be printed. Selecting the Maintain Test Results option in the Utilities
menu provides information for validating tests.
Figure 67 on page 137 shows an example of the Default Report of Calibration
produced by MET/TEMP II. The exact layout of this report depends on how
the test was performed and the type of data collected. If there is more informa-
tion than will fit on one page, additional pages are automatically generated.
The lower portion of this dialog determines the report template that will be
used when printing a Report or Calibration. If the Use default report template
option is selected, MET/TEMP II uses the built-in Report of Calibration tem-
plate. The Custom report template box and Browse button are disabled.
MET/TEMP II also allows custom report templates to be used when printing
reports. If the default report template isn’t exactly the type of report required
for your application, contact Hart application specialists for information on ob-
taining custom report templates designed to your specifications. If a custom re-
port template has been purchased from Hart, the Use custom report template
option allows the user to specify the file that contains the custom report tem-
plate. The Custom report template box and Browse button are enabled. Click
the Browse button to select the custom report template to use, then click the
Print button to launch the custom report template.
MET/TEMP II now comes with two custom Reports of Calibration which are
installed automatically when MET/TEMP II is installed. The custom report
files are installed in the \REPORTS folder and are named PASSFAIL.EXE and
HEATSRC.EXE. For more details on using these custom reports, see Section
11.2, Custom Reports of Calibration.
Note: Custom report template files MUST be located in the \REPORTS
subfolder of the C:\METTEMP2 folder (or the folder where MET/TEMP II was
installed) in order to operate properly.
Click the Fonts & Sizes button to specify the names, sizes and styles of the
fonts to be used when printing the default Report of Calibration and the custom

4.5.1 Heat Source Configuration Dialog
The Heat Source Configuration dialog is used to select the instrument(s) to use
as heat sources.
MET/TEMP II can use up to four heat sources to perform a calibration.
MET/TEMP II expects the reference probe and all test probes to be placed in
one heat source at a time. MET/TEMP II only supports a single reference
probe, therefore only one heat source can be used at a time. Multiple heat
sources can be used to increase the possible temperature range of a calibration.
When configuring the set-points for the calibration, each set-point must be as-
signed to a heat source. When using more than one heat source, the software
prompts the user throughout the calibration process to move the reference
probe and the test probes to the appropriate heat source.
Note: When using MET/TEMP II to calibrate a heat source, only one heat
source can be configured. Refer to Section 13, Performing Heat Source Cali-
brations, for more information on configuring MET/TEMP II to perform heat
source calibrations.
The Enable communications during configuration check box is provided to en-
able verifying communications with test equipment during the configuration
process. The default state of this check box is determined by the state of the

The Use heat sources as reference check box specifies that the heat source(s)
entered are to be used as the reference (the sensor(s) in the heat source(s) act as
the reference probe). When using the heat source(s) as the reference, the cali-
bration and recalibration dates are required.
When using MET/TEMP II to calibrate a heat source, the Use heat sources as
reference check box must be checked. This enables the Calibrate heat source
check box. To calibrate a heat source, select the Calibrate heat source check
box. When this feature is enabled, only one heat source can be configured. Re-
fer to Section 13, Performing Heat Source Calibrations, for more information
on configuring MET/TEMP II to perform heat source calibrations. When con-
figuring MET/TEMP II to calibrate a heat source, the calibration interval box
and Customer button are displayed and the calibration and recalibration date
boxes are hidden.
If not calibrating a heat source, select the number of heat sources to be used.
The maximum number of heat sources is four. The number of tabs displayed
corresponds to the number of heat sources selected.
Select the tab for the first heat source.
Heat source model numbers must be selected from the Model number
drop-down list. The manufacturer and description information is filled in auto-
matically when a model is selected. The model number is also displayed on the

When using MET/TEMP II to perform a calibration using only fixed-point
cells, the Fixed-Point heat source driver must be setup as a heat source. No
other heat source drivers need to be setup. When mixing fixed-points with com-
parison points, the Fixed-Point heat source driver may optionally be setup, but
is not required.
Next, select the serial number from the Serial number drop-down list or enter
the serial number in the Serial number box if it has not been entered previously.
MET/TEMP II records serial numbers, calibration dates and recalibration dates
to avoid having the user reenter the same data over and over.
The Calibration and Recalibration date information is only required if the Use
Heat Sources as reference check box is selected. Otherwise, this information is
optional.
If the recalibration date has passed and the Show recalibration date notification
messages check box on the Setup tab of the Defaults dialog is selected, the user
is warned and must change the calibration and recalibration dates before the in-
strument can be used.
Select the SmartSwitch port to which the instrument is connected using the
SmartSwitch port drop-down list. If the instrument is connected and powered
up at this time, make sure the Enable communications during configuration
check box is selected and click the Check Port button. MET/TEMP II will at-
tempt to establish communications with the instrument. If MET/TEMP II is not
able to communicate with the instrument, an error message is displayed. Other-
wise, a message is displayed stating communication was established with the
instrument. The SmartSwitch port box is disabled if the selected model number
is External or Fixed-Point.
Note: For dual-well heat sources such as the Model 9009 dry-well, each well
must be configured as a separate heat source (Model 9009C and Model 9009H)
with both heat sources assigned to the same SmartSwitch port. MET/TEMP II
allows the same SmartSwitch port to be assigned to more than one instrument
for dual well heat sources.
The Controller address is used only when the selected heat source is a Hart
9112 or 9113 furnace. The controller used in these instruments requires a
2-digit address when communicating through the serial port. Enter the control-
ler address in the Controller address box. For more details, see the Model 9112
or 9113 User’s Guide.
When the MET/TRACK link is active, the MT Asset number box is displayed.

heat source is to be used for during the calibration process. When configuring
set-points, each set-point must be assigned to a heat source. The temperature
range settings on this dialog can be used to restrict which set-points can be as-
signed to the selected heat source.
Note: Although MET/TEMP II allows the temperature range for any heat
source to be extended beyond its default temperature range, be aware that many
heat sources will not accept set-points that are outside the default temperature
range. This feature should only be used to restrict the temperature range for a
heat source.
When the External or Fixed-Point heat source drivers are selected, the tempera-
ture range defaults to –330 to 2650 degrees. These values can be changed if
desired.

5.1.1 Set-point Configuration Dialog
The Set-point Configuration dialog is used to configure the set-points to use for
the calibration.
Up to 40 set-points can be configured. MET/TEMP II allows set-points to be
set to 2 decimal places of precision. Most Hart heat sources can handle 2 deci-
mal places. Some heat sources, however, cannot. The set-points for the Model
9112 and 9113 furnaces are always rounded to the nearest degree.
Set-points are entered in the same temperature scale (C or F) as the heat
sources and reference scale. To change this scale, refer to Section 6, Scale
Menu. The default value for this scale can be changed on the Setup tab of the
Defaults dialog.
Set-points appear in the list in the order in which they will be used during the
test.
By selecting a set-point in the set-point list, the set-point value, window, toler-
ance, duration, and uncertainty associated with that set-point appear in the ap-
propriate boxes. If more than one heat source can be used for the set-point, all
heat sources that the set-point could be assigned to are displayed. If the selected
heat source is a bath, the Enable proportional band check box is displayed. If

this check box is selected, the Proportional band box is enabled. If not selected,
the Proportional band box is disabled.
A set-point is defined as the temperature that the reference probe should be
reading before MET/TEMP II begins taking measurements from the reference
probe and the test probes. Every comparison set-point must be assigned to one
of the configured heat sources. When the test processes a set-point, the refer-
ence probe and all test probes must be placed in the selected heat source for
that set-point. MET/TEMP II prompts the user at the appropriate time to place
all probes in the required heat source.
Fixed-point set-points are not assigned to a heat source.
Set-points can be generated automatically by clicking the Auto-Generate
Set-points button or inserted into the set-point list manually by clicking the In-
sert Set-Point or Insert Fixed-Point buttons. Set-points can be removed from the
set-points list by clicking the Remove Set-point or Remove All Set-points but-
tons. Each of these processes is explained in detail in the following sections.
Each set-point has its own window, tolerance, duration, uncertainty, and pro-
portional band settings that can be set independent from the other set-points.
The window and tolerance settings are not applicable to fixed-point set-points.
MET/TEMP II uses some of these parameters to determine when measurements
can begin. Refer to Figure 41, Example of Duration, Tolerance and Window
Settings.
The window parameter defines the desired accuracy to the set-point value (al-
lowable difference between the set-point and the reference probe reading). The
reference probe must be within the value of the window parameter of the
set-point value before MET/TEMP II will begin taking measurements. The ac-
tual set-point of the heat source may be adjusted automatically in order to bring
the reference probe readings within this window. For External heat sources,
MET/TEMP II prompts the user to adjust the heat source set-point manually, if
87

necessary. Because fixed-point set-points do not use a heat source, the window
parameter does not apply to fixed-point set-points.
The tolerance and duration parameters define the desired stability of the refer-
ence probe readings. These parameters are used by MET/TEMP II to determine
when the reference probe has stabilized at the current temperature. The toler-
ance parameter defines how much the reference probe readings may vary and
still be considered stable. The duration parameter is the length of time that the
reference probe readings must be stable before any measurements are taken.
Fixed-point set-points do not use the tolerance parameter. The duration parame-
ter is used to determine how long each test probe should be allowed to soak in
the fixed-point cell before MET/TEMP II begins taking measurements.
The uncertainty parameter is not used by MET/TEMP II to determine when
measurements are taken. In order for the Report of Calibration produced by
MET/TEMP II to meet the ANSI/NCSL Z540-1 specification, the uncertainty
at each set-point must appear on the report. The value entered in the uncertainty
box for each set-point appears on the Report of Calibration when printed. To
determine the uncertainty at a set-point, the uncertainty of each piece of equip-
ment used to take measurements at the set-point (i.e. reference readout, refer-
ence probe, scanner, heat source, etc.) must be known. The overall uncertainty
is generally the sum of these individual uncertainties.
Note: When using MET/TEMP II to calibrate a heat source, the value entered
in the Uncertainty box for each set-point appears on the custom Heat Source
Report of Calibration as the Tolerance and is used to determine the pass/fail
status at each set-point. Refer to Section 13, Performing Heat Source Calibra-
tions, and Section 11.2.2, Heat Source Report of Calibration, for more details.
The proportional band parameter can be used only when the selected heat
source for a set-point is a Hart bath. The controller for a bath can be fine tuned
for optimal performance at a specific set-point by adjusting the proportional
band parameter. By selecting the Enable proportional band check box,
MET/TEMP II will set the proportional band parameter of the bath to the speci-
fied value when the test begins to process the set-point. If the Enable propor-
tional band check box is not checked, the proportional band parameter of the
bath will not be changed.
Every time this dialog is displayed, each set-point is checked to make sure it
falls within the range of the heat source that was previously selected for the
set-point. If any of the heat source configuration information has changed, the
user may be required to reselect the heat source to which each set-point is
assigned.
To open a set-point configuration file, click the Open button. The Windows®
Open dialog is displayed. A previously saved set-point configuration file (.STC
or .STF) can be opened. When opening a set-point configuration file, all cur-
rent set-points will be overwritten. Refer to Section 10.2, Set-point Configura-
tion File, for additional information on opening a set-point configuration file.
Note: When calibrating a heat source, a set-point configuration file that con-
tains the set-points to use to calibrate the heat source must be opened before

5.1.1.2 Inserting Comparison Set-points
Comparison set-points can be manually inserted into the set-point list by click-
ing the Insert Set-point button. All set-points generated using this process are
considered comparison set-points.
Note: When calibrating a heat source, a set-point configuration file must be
opened before set-points can be manually inserted.
To insert a set-point to the set-point list manually, first select the set-point in the
set-point list that the new set-point should come before. To add a set-point to
the top of the set-point list, select the first set-point in the list. To add a
set-point to the end of the list, select the <new set-point> item in the list.
Click the Insert Set-point button. The cursor is placed in the set-point box. En-
ter the value of the new set-point and press <Enter>. The new set-point is in-
serted into the set-point list. The window, tolerance, duration, and uncertainty
parameters are automatically set to their default settings as defined on the
Set-points tab of the Defaults dialog. To abort inserting a new set-point, press
<Esc>.
If the new set-point falls outside the defined temperature range of the config-
ured heat sources, a message appears and the set-point is not inserted into the
list. If two or more heat sources can be used for the new set-point, the set-point
is inserted into the list and the user must select the heat source for the set-point
to use. If only one heat source can be used, the heat source is automatically se-
lected and appears in the set-point list with the set-point.
If the window, tolerance, duration, uncertainty, or heat source settings need to
be changed, follow the instructions in Section 5.1.1.5, Editing Set-points.
5.1.1.3 Inserting Fixed-Point Set-points
MET/TEMP II was originally designed to do comparison calibrations only, but
support has been added for fixed-points also.
To insert a fixed-point set-point to the set-point list manually, first select the
set-point in the set-point list that the new fixed-point set-point should come be-
fore. To add a fixed-point set-point to the top of the set-point list, select the first
set-point in the list. To add a fixed-point set-point to the end of the list, select
the <new set-point> item in the list.

Click the Save button to save the new uncertainty settings, then click the OK
button to close this dialog. Clicking the Cancel button discards any changes and
closes this dialog.
Note: The uncertainty parameter is not used by MET/TEMP II to determine
when measurements are taken. In order for the Report of Calibration produced
by MET/TEMP II to meet the ANSI/NCSL Z540-1 specification, the uncer-
tainty at each set-point must appear on the report. To determine the uncertainty
at a set-point, the uncertainty of each piece of equipment used to take measure-
ments at the set-point (i.e. reference readout, reference probe, scanner, heat
source, etc.) must be known. The overall uncertainty is generally the sum of
these individual uncertainties.
Note: When using MET/TEMP II to calibrate a heat source, the value entered
as the uncertainty for each set-point appears on the custom Heat Source Report
of Calibration as the Tolerance and is used to determine the pass/fail status at
each set-point. Refer to Section 13, Performing Heat Source Calibrations, and
Section 11.2.2, Heat Source Report of Calibration, for more details.

Calibration Menu
1.888.610.7664 sales@GlobalTestSupply.com
Fluke-Direct.com
The Test Probe Configuration dialog is used to configure the test probes
(UUTs) to be calibrated.
Important: When using MET/TEMP II to calibrate a heat source, the
scanner instrument acts as the reference instrument and the test probe acts
as the reference probe. The calibration and recalibration date boxes are
only displayed when calibrating a heat source. The calibration interval
and Customer button are hidden when calibrating a heat source.
The Scanner or Modules list in the upper left corner of this dialog displays a
list of the currently configured scanner or scanner modules. The Channels list
displays a list of the channels on the scanner or scanner module that is cur-
rently selected in the Scanner or Modules list.
Note: If the Do not use scanner – prompt to manually enter all readings option
on the Scanner Configuration dialog is selected, the Scanner list is empty and
the Probes list allows up to 100 test probes to be configured. All readings for
these probes must be entered manually. MET/TEMP II displays a prompt for
the data to be entered at the appropriate times during the calibration process.

If the same instrument is being used as both the reference readout and the scan-
ner, the channel that is currently configured with the reference probe appears in
the Channel list with the <Reference> marker. A test probe cannot be config-
ured on this channel. When this channel is selected, the Clear Channel button,
Model number, Serial number, and other controls on this dialog are disabled.
Clicking the Clear All Channels button removes all test probe configuration in-
formation from all channels, regardless of the scanner or scanner module that is
currently selected. This button may be clicked to make sure all channels are
cleared before beginning to configure test probes.
Clicking the Clear Channel button removes test probe configuration informa-
tion from the currently selected channel only.
To configure a test probe, select the appropriate scanner or scanner module
from the Scanner or Modules list, as applicable. Then select the channel to
which the test probe is connected in the Channels list. If MET/TEMP II is con-
figured to not use a scanner, simply click any entry in the Probes list. The order
of the test probes is not important, but MET/TEMP II will prompt for the data
for each test probe to be manually entered in the order in which the test probes
are configured in this list.
Important: When using the Hydra series dataloggers with 4-wire probes,
configure the probes on the first channel that the probe is connected to.
For example, if a 4-wire probe is connected to channels 4 and 14, config-
ure the probe in MET/TEMP II on channel 4 and DO NOT ATTEMPT TO
CONFIGURE A PROBE ON CHANNEL 14! Leave that channel blank.
Next, select the test probe model number using the Model number drop-down
list. The probe type, manufacturer and description information is filled in auto-
matically when a model number is selected. If the model number does not ap-
pear in the list, enter the model number in the Model number box. MET/TEMP
II only displays probes of the type that can be used on the selected scanner or
scanner module. If a scanner is not being used, the user can select from all pos-
sible probe types. Select the probe type and enter the manufacturer and descrip-
tion for the test probe in the Manufacturer and Description boxes. MET/TEMP
II records model numbers, probe type, manufacturer and description informa-
tion to avoid having the user reenter the same data over and over.
The probe type must be selected from the Probe type list. Available probe types
depend on the type of scanner or scanner module selected. Possible probe types
are:
• SPRT
• RTD 385 3-wire or 4-wire
• RTD 392 3-wire or 4-wire
• RTD 2-wire, 3-wire or 4-wire
• Other PRT/RTD

Next, select the serial number from the Serial number drop-down list or enter
the serial number in the Serial number box if it has not been entered previously.
Select the calibration interval, report units and excitation current or CJC read-
ings settings for the test probe as applicable in the boxes provided. MET/TEMP
II records serial numbers, calibration intervals, report units, and excitation cur-
rent/CJC readings settings to avoid having the user reenter the same data over
and over.
The calibration interval is the number of days, from the date the calibration is
performed, until the next calibration is due. The calibration interval can be in-
cremented in steps of 30 days using the up/down buttons or entered manually.
The allowable range is 0 to 730 days (2 years). If the calibration interval is set
to 0, the recall date does not print on the Report of Calibration.
The report units are the scale of the test probe readings. The possible choices
are:
• C
• F
• K
• Ohms (except thermocouple, LIG, and Bi-metallic probes)
• mV (except resistance, LIG, and Bi-metallic probes)
During a calibration test, MET/TEMP II attempts to verify that the test probe
and reference probe readings are in the correct scale. For this reason, it is im-
portant to manually set each scanner channel to read in the appropriate scale
before starting a calibration test.
Note: In order to calculate characterization coefficients and generate ta-
bles, the test probe report units must be in one of the non-temperature
scales (Ohms or mV).
The excitation current setting is shown if the test probe is a resistance type
probe and the scanner instrument or module supports setting the excitation cur-
rent. Make sure the setting for the excitation current in the scanner instrument
or module matches the setting in MET/TEMP II for each channel before start-
ing a test. The excitation current must be selected from the Current drop-down

list. Available excitation current settings depend on the type of scanner or mod-
ule selected. Possible currents are:
• 2µA, 10µA, 30µA
• 0.05 mA, 0.1mA, 0.2mA, 0.5mA, 1mA, 1.4mA, 3mA, 5mA
• Auto or N/A
Note: The excitation current should be set manually in the scanner instru-
ment before starting the calibration test because not all scanner instru-
ments support setting the excitation current via serial communication
commands.
The CJC reading setting is available if the test probe is a voltage type probe.
This is the Cold Junction Compensation setting. This setting is used to tell
MET/TEMP II whether or not to take CJC readings at each temperature. Select
Enabled if CJC readings should be taken, or select N/A if CJC readings are not
required or compensation is handled internally within the Scanner instrument
for this test probe.
Generally, the CJC option should be set to N/A when the report units for a
given test probe are in temperature and Enabled when the report units are in
voltage. Hart instruments automatically account for CJC when configured to
display measurements in temperature, but do not account for CJC when config-
ured to display measurements in voltage.
Note: For the Hart Model 1560 “Black Stack” and Model 1529
“Chub-E4”, CJC readings are ALWAYS taken in degrees C. See the instru-
ment’s User’s Guide for more information about the CJC settings.
When calibrating a heat source, the Calibration date and Recalibration date
boxes are displayed. Enter the calibration and recalibration dates for this probe.
Clicking the Customer button displays the Customer Information dialog for en-
tering more information about the selected test probe. Refer to Section 5.4.1.1,

Note: The only situation where MET/TEMP II allows two instruments to
be assigned the same SmartSwitch port is when using a dual-well heat
source that has two separate controllers but a single communication port.
After checking the configuration information, MET/TEMP II attempts to com-
municate with each instrument. If communication with any instrument fails, a
communication error dialog is displayed. MET/TEMP II will automatically re-
try the communication every 5 seconds or when the Retry button is clicked.
Read this dialog and check the indicated items to determine why MET/TEMP
II cannot communicate with the instrument. Clicking the Cancel button aborts
starting the calibration test.
Note: MET/TEMP II will not attempt to communicate with External heat

Note: The current configuration is always saved at this point to a file
named 9938LAST.CFG. Opening this configuration file will always restore
the configuration settings most recently used to run a calibration test.
The Test Information dialog is then displayed. Refer to Section 5.5.2, Test In-
formation Dialog, for more information.
Once all of the information on the Test Information dialog has been entered and
the test is running, MET/TEMP II prompts to make sure that all of the refer-
ence readout and scanner channels are configured to read the correct scales and
to insert the reference probe and all test probes into the heat source for the first
set-point.
MET/TEMP II then waits for the heat source to reach the set-point and stabilize
according to the tolerance and duration parameters for the current set-point. Be-
fore taking measurements from the reference and test probes, MET/TEMP II
checks to ensure that the difference between the desired set-point temperature
and the current reference reading does not exceed the window parameter for the
current set-point. If it does, the heat source set-point is recalculated to compen-
sate for the error and the stabilization process repeats.
MET/TEMP II then begins to take measurements from the first test probe and
the reference. The number of readings that are taken is defined on the Test tab
of the Defaults dialog. Then this process is repeated for the second test probe,
etc. When readings have been taken from all test probes, MET/TEMP II ad-
vances to the next set-point. A prompt is displayed if the reference and test
probes need to be moved to a different heat source at this time.
When MET/TEMP II has repeated this process for all set-points, the test pro-
cess ends. Select the Close Test option in the File menu to close the test.
If the calibration test was configured to not use a scanner instrument, the Enter
Data dialog is displayed at the appropriate times to allow the readings for the
indicated test probe to be manually entered. Refer to Section 5.5.1, Enter Data
Dialog, for more information on using this dialog.
If MET/TEMP II was configured to use an External heat source or one or more
fixed-point set-points, MET/TEMP II displays a prompt at the appropriate
times to manually set the heat source temperature or to place the test probes
one at a time into the fixed-point cell. Refer to Section 12, Performing Calibra-
tions Using Fixed-Points for more information.
If MET/TEMP II was configured to take ambient temperature and humidity
readings from a Model 1620/5020A ‘DewK’ Thermohygrometer, the ‘DewK’ is
queried at regular intervals throughout the entire test. When the test is complete
or aborted, the average of the ambient temperature and humidity readings over
the entire test period are calculated and written to the database.

The Test Information dialog displays some general settings that apply to all test
probes for this test. Most of the settings on this dialog are remembered from the
settings that were used for the previous test.
The Full range calibration and Partial range calibration options are used to
specify whether the test probes are being calibrated over their full range or over
a partial range. Select the appropriate option.
Enter the name of the technician performing this test in the box provided. This
name is automatically filled in using the name from the User tab on the De-
faults dialog. This name appears on the Report of Calibration below one of the
signature lines.

The Test date is the date the test begins and defaults to today’s date. If the date
is incorrect, check the clock on the computer. To change the test date, use the
drop-down calendar and click on the appropriate date.
In the Test procedure box, enter the name or document control number of the
in-house document that describes the method or procedure followed when per-
forming this test.
Select the Preheat heat sources check box if you want MET/TEMP II to preheat
each heat source prior to being used in the test process. If this option is se-
lected, MET/TEMP II always looks ahead one set-point to determine if that
set-point is assigned to a different heat source than the current set-point. If so,
the heat source is set to its first set-point. If an External heat source is being
used, the user is prompted to manually set the set-point of the heat source. This
feature can save time in performing calibrations. If only one heat source is be-
ing used, selecting this option has no effect.
The Reference/UUT reading resolution drop-down list is used to specify the
resolution that MET/TEMP II should use to format all reference and test probe
readings. This setting applies to temperature, resistance and voltage readings.
All reference and test probe readings taken by MET/TEMP II for the current
test will be formatted to the selected number of decimal places. This setting
should be set appropriately according to the configured resolution of the read-
ings for each instrument as well as the calibration test requirements. An exam-
ple reading is displayed next to the drop-down list.
If the Generate test number automatically check box is selected, the test num-
ber is automatically generated by using the initials of the technician performing
the test, the four digits of the current year, two digits of the current month, and
a three digit sequence number. The test number box is disabled.
If the Generate test number automatically check box is not selected, the test
number box is enabled and the user must enter a test number. The test number
must be unique. MET/TEMP II will make sure the entered test number is
unique when the OK button is clicked.
The default state of the Generate test number automatically check box is deter-
mined by the setting on the Setup tab of the MET/TEMP II Defaults dialog.
Clicking on the Paragraph and Notes buttons allow text files that contain text to
appear on the Report of Calibration to be selected. When clicking either of
these buttons, the Text Editor dialog is displayed. Refer to Section 3.4.5.1, Text
Editor Dialog, for more details on using this dialog.
Note: The text for the paragraph and notes must be saved to a file in order
to appear on the Report of Calibration. A default paragraph file can be
defined on the Reports tab of the Defaults dialog. The notes must be speci-
fied for every test.
If the Get ambient conditions from ‘DewK’ check box on the General tab of the
MET/TEMP II Defaults dialog is checked, MET/TEMP II will attempt to query

the ambient temperature and humidity readings from a Model 1620/5020A
‘DewK’ Thermohygrometer using the settings defined on the General tab.
MET/TEMP II queries readings from the connected ‘DewK’ throughout the test
process and writes the average ambient temperature and humidity readings to
the database when the test is complete. If this check box is not checked, manu-
ally enter the ambient temperature, temperature scale, and humidity in the
boxes provided. This information is printed on the Report of Calibration.
Clicking the OK button checks to make sure the test number is unique and then
begins the test process.
Note: If the test number is not unique (a test already exists with that test
number), the user is prompted to overwrite the existing test or to enter a
new test number. Selecting to overwrite the existing test must be confirmed
because overwriting a test is permanent; all data from the existing test is
deleted!
Clicking the Cancel button returns to the MET/TEMP II Main Display without
starting a test.
5.6
Stop Test
The Stop Test option aborts the current calibration test. This option does not
appear in the menu unless a test is currently running. When aborting a test, a
prompt is displayed to confirm aborting the test.
Once a test has been aborted, it cannot be resumed. Select the Pause Test option
to pause a test temporarily. MET/TEMP II continues to take readings from and
graph the reference after a test has been aborted until the Close Test option in
the File menu is selected.
5.7
Pause Test
The Pause Test option suspends the test process. This option does not appear in
the menu while a test is paused. This feature can be used to temporarily pause
the test for any reason.
Important: A calibration test should not be paused for long periods of
time, such as overnight!
Note: A calibration test cannot be paused when readings are being taken from
the reference and test probes. This option is disabled until all readings have
been taken at the current set-point.

5.9.1 Stability Override Dialog
The Stability Override dialog displays the settings associated with the current
set-point. These parameters can be modified or overridden using this dialog.
To override the current set-point parameters, select the Take readings now op-
tion. When the OK button is clicked, the test process will automatically start
taking readings from the reference and test probes, regardless of whether the
heat source has reached and stabilized at the current set-point.
Note: MET/TEMP II can be configured to automatically override the
set-point parameters after a certain period of time on the Test tab of the
Defaults dialog.

When overriding set-point parameters, the current set-point is marked as over-
ridden. Set-points that have been overridden appear on the Report of Calibra-
tion with a special marker and a note indicating that the set-point parameters
were overridden for that set-point.
To change the window parameter for the current set-point, enter the new value
in the Window box. The window parameter is used to determine if a new
set-point needs to be calculated for the heat source. If MET/TEMP II gets stuck
in a loop recalculating the heat source set-point, this parameter can be changed
to widen the acceptable window. Typically, however, when MET/TEMP II gets
stuck in such a loop, the tolerance and duration parameters need to be changed.
To change the tolerance parameter for the current set-point, enter the new value
in the Tolerance box. The tolerance parameter is used with the duration param-
eter to determine when the heat source has stabilized at the current set-point.
Setting the tolerance parameter too large may cause MET/TEMP II to prema-
turely determine that the heat source has stabilized at the set-point and may
proceed to check the window parameter and calculate a new set-point for the
heat source. Setting the tolerance parameter too small may cause MET/TEMP
II to determine that the heat source will never stabilize and, therefore, never
proceed to taking measurements.
To change the duration parameter for the current set-point, enter the new value
in the Duration box. The duration parameter is used with the tolerance parame-
ter to determine when the heat source has stabilized at the current set-point.
Setting the duration parameter too short may cause MET/TEMP II to prema-
turely determine that the heat source has stabilized at the set-point and may
proceed to check the window parameter and calculate a new set-point for the
heat source. Setting the duration parameter too long may cause MET/TEMP II
to determine that the heat source will never stabilize and, therefore, never pro-
ceed to taking measurements.
Click the OK button to accept the new parameter settings, close the dialog and
return to performing the test. Clicking the Cancel button aborts changing the
parameter values and closes the dialog.

tabases, to maintain the tables used for storing the test equipment and test re-
sults, to run the Coefficients and Tables application, and to export test data to
Fluke’s MET/TRACK software.
8.1 Compact Database
Selecting the Compact Database option allows any deleted records in the
MET/TEMP II databases to be purged from the database. Using this option
from time to time can typically reduce the size of the database and make ac-
cessing the database faster.
Selecting the Compact Database option displays the Windows® Open dialog.
Select the database file to compact and click the OK button. Clicking the Can-
cel button aborts compacting a database.
When MET/TEMP II compacts a database, a copy of the database is made and
given a .BAK extension. If a .BAK file with the same name already exists, it is
deleted and replaced by the new .BAK file.
8.2 Repair Database
Selecting the Repair Database option allows a corrupted MET/TEMP II data-
base to be repaired. A database can become corrupted if there is a power failure
or if the software terminates abnormally or crashes. Typically, if a database is

Important: Use caution when removing tests. Once a test has been re-
moved it no longer exists! All data is deleted permanently. For this reason
the user is asked to confirm the removing of tests from the database!
MET/TEMP II stores test data in separate tables within the database. If a test is
stopped before any readings are taken, the table containing the readings has no
records for that test. If the database becomes corrupt, some of the data for a
particular test may be lost. These are a couple of the reasons why the user may
need to validate the test.
The validation feature of MET/TEMP II can be used to determine if there are
records for every test in every table.
Clicking the Validate or Validate All buttons performs a check on the selected
tests to see if there are records in each of the database tables for the test. If
MET/TEMP II determines that a test is invalid, the Invalid Test dialog is dis-
played. Otherwise, a message appears stating the validity of the tests.
Note: This feature does not determine the validity of readings taken by
MET/TEMP II. It determines only if a test valid based on the presence or
absence of information for the test in the database.
8.4.1.1 Invalid Test Dialog
The Invalid Test dialog displays information about the test that is being vali-
dated. The Test is invalid for the following reasons list shows the reasons why
the test is considered to be invalid. If no readings were found for one or more

the test as is. Selecting the Remove this test option permanently removes the
entire test from the database. Selecting the Remove selected probes option al-
lows the user to remove information specific to one or more test probes from a
test while leaving the other test probes and the test itself intact. To use this op-
tion, select the test probe(s) that should be removed from the list on the lower
left.
Clicking the OK button performs the selected option and continues on to the
next test or returns to the Maintain Test Results dialog. Clicking the Cancel but-
ton closes this dialog and ignores the selected option.

10 Configuration Files
MET/TEMP II supports writing current configuration information to configura-
tion files to make the test instrument, set-point and test probe configuration
process much easier. Instrument, set-point and test probe configuration files can
be saved independent of each other to provide maximum flexibility. Each of the
sections below describes the configuration files supported by MET/TEMP II.
10.1 Instrument Configuration File
An instrument configuration file contains information concerning the commu-
nications settings, reference readout, scanner, and heat source instruments in-
cluding model numbers, serial numbers, and other information required by the
software. The default extension for an instrument configuration file is .CFG.
These files are usually saved in the \CONFIG subfolder.
Instrument configuration files can be opened by selecting the Open option in
the File menu or by clicking the Open button on the Equipment Info dialog.
Important: Opening an instrument configuration file completely replaces
the current instrument configuration information.
When an instrument configuration file is opened, MET/TEMP II attempts to re-
trieve the driver and calibration information for each instrument. If any con-
flicts or errors are detected while opening an instrument configuration file,
messages are displayed providing some information as to the problems found.
The user must follow the instructions given by the messages to correct the
problems before a test can begin.
Instrument configuration files can be saved at any point during the configura-
tion process by selecting the Save As option in the File menu or by clicking the
Save As button on the Equipment Info dialog. The user is prompted to enter a
filename for the configuration file. All instrument configuration files should be
saved in the \CONFIG subfolder with a .CFG extension
The default instrument configuration file, 9938LAST.CFG, is automatically
saved every time a test starts and when the software terminates regardless of
whether or not the user explicitly saves the configuration.
Important: The format of the instrument configuration file has changed
slightly in this version of MET/TEMP II from previous versions (formerly
Calibrate-it) due to enhancements and newly supported instruments. For
this reason, MET/TEMP II may not be able to successfully read in instru-
ment configuration files from previous versions. Therefore, any instrument
configuration file from a previous version of this software should be saved
in this version using the same filename.

10.2 Set-point Configuration File
A set-point configuration file contains a set of set-points that can be used for a
test. The default extension for a set-point configuration file is either .STC or
.STF. Set-point configuration files with a .STC extension are for set-points in C
and .STF files are for set-points in F. These files are usually saved in the
\CONFIG subfolder.
When calibrating a heat source, a set-point configuration file MUST be opened.
When MET/TEMP II was installed, the default heat source calibration set-point
configuration files were written to the \CALFILES subfolder in the \CONFIG
subfolder.
Set-point configuration files can be opened by clicking the Open button on the
Set-point Configuration dialog.
Important: Opening a set-point configuration file completely replaces the
current set-point configuration.
Set-point configuration files contain the set-point values, window, tolerance,
duration, uncertainty, fixed-point cell and proportional band information as ap-
plicable for each set-point. Information regarding the heat source assignment is
not saved in this file. If the configuration file being opened is not of the same
temperature scale as the heat sources, a message is displayed. Click Yes to con-
vert the heat sources to the same scale as the set-points or click No to abort
opening the set-point configuration file.
When a set-point configuration file is opened, MET/TEMP II automatically at-
tempts to assign each set-point to a heat source if the Prompt for heat source
conflicts check box on the Set-points tab of the Defaults dialog is selected. If a
set-point does not fall within the temperature range of any of the configured
heat sources, a message is displayed and the set-point is excluded from the test.
If the Prompt for heat source conflicts check box is not selected, set-points are
not automatically assigned to heat sources. Each set-point must be assigned to a
heat source manually using the Set-point Configuration dialog.
Important: A test cannot begin until all set-points have been assigned to a
heat source.
If more than one heat source can be used for that set-point, the Set-point Op-
tions dialog is displayed. The user is asked to choose the heat source to use
and/or the proportional band setting. Refer to Section 10.2.1, Set-point Options
Dialog, for more information on using this dialog.
Set-point configuration files can be saved by clicking the Save As button on the
Set-point Configuration dialog. The user is prompted to enter a filename for the
configuration file.

10.2.1 Set-point Options Dialog
The Set-point Options dialog is used when auto-generating set-points or when
opening a set-point configuration file to resolve heat source conflicts when
more than one heat source can be used for a set-point.
This dialog displays the heat sources that can be used for the indicated
set-point. Select which heat source the indicated set-point should use by click-
ing the appropriate option button. Selecting a heat source other than a bath will
cause this dialog to immediately close. This is done to speed up the process of
selecting heat sources to use. If the selected heat source is a bath, the propor-
tional band information is displayed and the user is allowed to setup the pro-
portional band settings at this time. In this case, the OK button must be clicked
to accept the settings and continue.
The Enable proportional band check box is visible only when the indicated
set-point is assigned to a bath. If this check box is selected, a proportional band
value is expected to be entered. The proportional band value is sent to the bath
during the test process when the bath is set to the indicated set-point.
Click the OK button to accept the current settings and close this dialog. Click-
ing the Cancel button leaves the indicated set-point unassigned.
10.3 Test Probe Configuration File
A test probe configuration file contains information concerning the set of test
probes to be calibrated including scanner channel information, probe model
numbers, serial numbers and customer information. The default extension for a

test probe configuration file is .TPC. These files are usually saved in the
\CONFIG subfolder.
Test probe configuration files can be opened by clicking the Open button on the
Test Probe Configuration dialog.
Important: Opening a test probe configuration file completely replaces
the current test probe configuration.
Test probe configuration files are partially dependent on the scanner instrument
configuration. Because some scanner information is saved in the test probe con-
figuration file for compatibility reasons, attempting to open a test probe config-
uration file will most likely fail when the currently configured scanner differs
from the information in the configuration file. Warning and/or error messages
may appear in this situation. When MET/TEMP II opens a test probe configu-
ration file, it attempts to retrieve scale, current/CJC, customer name, and cus-
tomer address information for each probe. If any conflicts or errors are detected
while opening an instrument configuration file, messages are displayed provid-
ing some information as to the problems found.
The user must enter the order ID number for each test probe when a configura-
tion file is opened. If the Prompt for order ID when opening Test Probe Config-
uration file check box on the Setup tab of the Defaults dialog is selected, the
Enter Order ID dialog appears. If the Prompt for Order ID when opening Test
Probe Configuration file check box is not selected, the user must manually en-
ter this information on the Customer Information dialog by clicking the Other
Info button on the Test Probe Configuration dialog. Refer to Section 10.3.1,
Enter Order ID Dialog, for more information on using this dialog.
Test probe configuration files can be saved by clicking the Save As button on
the Test Probe Configuration dialog. The user is prompted to enter a filename
for the configuration file.

10.3.1 Enter Order ID Dialog
The Enter Order ID dialog is used when opening a test probe configuration file
to associate an order ID number with each test probe.
This dialog displays the model and serial numbers of the test probe and allows
the order ID number to be entered. This number can be a purchase order, work
order, sales order or any other such number.
This dialog is only displayed if the Prompt for order ID when opening Test
Probe Configuration file option on the Setup tab on the Defaults dialog is se-
lected. If this option is not selected, no order ID number is associated with the
test probes. The order ID number for each test probe must be manually entered
on the Customer Information dialog. Refer to Section 5.4.1.1, Customer Infor-
mation Dialog, for more information.
Selecting the Use same order ID number for all subsequent probes option
causes the same order ID number to be associated with the remainder of the test
probes. This dialog will not be displayed again. If not selected, this dialog will
be displayed once for every test probe to allow a different number to be
entered.
After entering the order ID number, click the OK button to accept it and close
this dialog.

11 Reports of Calibration
This section describes in detail the default Report of Calibration that is built
into MET/TEMP II and the custom Reports of Calibration that ship with
MET/TEMP II.
Custom report template files are installed in the \REPORTS subfolder of the
C:\METTEMP2 folder (or the folder where MET/TEMP II was installed).
11.1 Default Report of Calibration
The default Report of Calibration in MET/TEMP II was designed to meet the
ANSI/NCSL Z540-1 specification (refer to Figure 67 on page 137).
The default Report of Calibration contains: the report number, the test probe in-
formation, calibration range, received condition, excitation current used (if ap-
plicable), test procedure, customer name and address, calibration test paragraph
and notes, the actual data collected, a list of the test equipment, calibration
date, recall date, ambient temperature and humidity, customer order ID, techni-
cian name, and a place for technician and approval signatures. The actual data
collected consists of the nominal values (set-points), actual values (reference
readings), UUT values (test probe readings), error (if applicable), uncertainty,
CJC readings (if applicable), and method of realization.
The fonts, sizes, and styles used on the default Report of Calibration can be
changed on the Fonts & Sizes tab of the Defaults dialog.
The top, bottom, left, and right margins and the column widths for the Test
Equipment table on the Report of Calibration can be set using the appropriate
controls on the Reports tab of the MET/TEMP II Defaults dialog. A custom
logo can also be added to the upper left corner of the Report of Calibration us-
ing the settings on this tab.
Reports of Calibration can be saved to a report file from the Print Preview win-
dow and opened, viewed and printed by selecting the Recall Saved Report op-
tion from the File menu or by running the Report Viewer utility. Refer to
Section 17, Report Viewer Utility, for more details.
The report number is printed on each page of the Report of Calibration. The re-
port number is a unique number consisting of the test number and the scanner
channel to which the test probe was connected. These two pieces of informa-
tion are concatenated together with a dash.
The test probe information consists of the test probe model number, serial num-
ber and description. This information is printed at the top of the first page along
with the calibration range, received condition, excitation current used, and test
procedure number.
The paragraph text is the text entered as the paragraph on the Test Information
dialog. The default paragraph to use can be defined on the Report tab on the
Defaults dialog.

The raw data section contains the readings taken by the software. If the Stabil-
ity Override menu option was used on any set-point during the test, the
set-point will be marked and a footnote will appear at the bottom of the raw
data section stating that the stability parameters were overridden for the
set-points indicated. The raw data section may be different depending on the
type of test probe being calibrated, the units of the readings taken, and the in-
struments used to take the readings.
• The Nominal Value, Actual Value, UUT, and Measurement Uncertainty
columns always print.
• The Error column prints only if the units for the Actual Value and UUT
columns are in temperature and are the same scale.
• The CJC column prints only if the test probe is a thermocouple type probe
and CJC readings were taken.
• The Method of Realization column prints only if the test was performed
using MET/TEMP II v4.0 or later.
The Test Equipment section lists each of the instruments that were used to per-
form the calibration. Each instrument’s manufacturer, model, description, serial
number and recall date is indicated. For instruments that do not require calibra-
tion, NCR is printed in the Recall Date column.
The notes text is the text entered as the notes on the Test Information dialog.
The calibration date is the date the test started. This date is entered on the Test
Information dialog.
The recall date is the date the test probe or test equipment is due for
recalibration. For the test probe, this date is calculated by adding the calibration
interval entered on the Test Probe Configuration dialog to the calibration date.
For the test equipment, the user enters this date on the configuration dialogs.
Recall date is synonymous with recalibration date.
Note: If the calibration interval is set to 0 on the Test Probe Configuration
dialog, the recall date is omitted from the Report of Calibration for that
test probe.
The technician is the name of the person who performed the test. This informa-
tion is entered on the Test Information dialog.
Examples of default Reports of Calibration can be seen in Figures 67 and 68,
on pages 137 and 138.

11.2 Custom Reports of Calibration
MET/TEMP II supports using custom reports of calibration. If the default re-
port template isn’t exactly the type of report required for your application, con-
tact Hart sales representatives for information on obtaining custom report
templates designed to your specifications.
MET/TEMP II ships with two custom reports of calibration. These reports are
described in the following sections.
11.2.1 Pass/Fail Report of Calibration
MET/TEMP II comes with a custom Report of Calibration that is designed to
print a tolerance and a pass/fail status associated with each set-point on the
report.
Note: The tolerance that prints on this report is not the same as the toler-
ance specified on the Set-point Configuration dialog when the test was
configured. This report prompts for the tolerance to be entered the first
time the report is printed for each test probe.
To print the Pass/Fail Report of Calibration, select the Use custom report tem-
plate option on the Print Test Report dialog and select the PASSFAIL.EXE re-
port template. Click the Print button. The Print Custom Report of Calibration
dialog is displayed.

To use this custom report, you must select either a test number or a model num-
ber on which to base the test probe selection.
If the test number option is selected, a list of test numbers becomes available.
Once a test number is selected, the probe model numbers and serial numbers
appear below. From the list entitled Select probes, select the probe model num-
ber and serial number.
If the model number option is selected, a list of probe model numbers becomes
available. Once a model number is selected, the probe serial numbers and test
numbers appear below. From the list entitled Select probes, select the probe test
number and serial number.
Select the test probes in the Select probes list.
If the Print all reports for this test number check box is selected, a Report of
Calibration is printed for the selected test probes. If not selected, reports are
printed only for the highlighted test probes in the Select probes list.
If the Preview report checkbox is selected, the report is displayed in the Print
Preview window. If the Preview report check box is not selected, the report is
sent directly to the printer.
Clicking the Print button prints the Pass/Fail Report of Calibration for the se-
lected probes. If this is the first time this report is being printed using this cus-
tom report, the Tolerance dialog is displayed.
Clicking the Exit button closes the Print Custom Report of Calibration dialog.
The Pass/Fail Report of Calibration contains: the report number, the test probe
information, calibration range, received condition, excitation current used (if
applicable), test procedure, customer name and address, calibration test para-
graph and notes, the actual data collected, a list of the test equipment, calibra-
tion date, recall date, ambient temperature and humidity, customer order ID,
technician name, and a place for technician and approval signatures. The actual
data collected consists of the actual values (reference readings), UUT values
(test probe readings), error, tolerance, uncertainty, result (pass/fail), and CJC
readings (if applicable).
The fonts, sizes and styles used on the Pass/Fail Report of Calibration can be
changed on the Fonts & Sizes tab of the Defaults dialog.
The top, bottom, left, and right margins and the column widths for the Test
Equipment table on the Pass/Fail Report of Calibration can be set using the ap-
propriate controls on the Reports tab of the MET/TEMP II Defaults dialog. A
custom logo can also be added to the upper left corner of the Pass/Fail Report
of Calibration using the settings on this tab.
To use this custom report, select the Use custom report template option on the
Print Test Report dialog. Click the Browse button and select the
PASSFAIL.EXE file in the \REPORTS subfolder. Clicking the Print button on
the Print Test Report dialog launches this custom report.

Reports of Calibration can be saved to a report file from the Print Preview win-
dow and opened, viewed and printed by selecting the Recall Saved Report op-
tion from the File menu, or by running the Report Viewer Utility. Refer to
Section 17, Report Viewer Utility, for more details.
The layout of this custom report is nearly identical to the default report ex-
plained in section 11.1, Default Report of Calibration. Notable differences are
indicated below:
• This custom report requires the test probe readings to be taken in the same
scale as the reference probe readings (C or F). If the test probe readings
are taken in resistance or voltage, this report cannot be printed.
• The Tolerance column in the raw data section of this report displays the
values entered by the user on the Tolerance dialog. The scale of the values
in this column is based on the scale of the values in the UUT column (C
or F). Each set-point on the report has its own associated tolerance value.
• The Result column in the raw data section of this report displays the
pass/fail status of the test probe at each set-point. This column displays ei-
ther the word Pass if the value in the Error column is less than or equal to
the value in the Tolerance column. Otherwise, the word Fail is displayed
in this column.

11.2.1.1 Tolerance Dialog
The Tolerance dialog allows the tolerance value for each set-point on the
Pass/Fail Report of Calibration to be entered.
The tolerance value must be entered exactly as it should be printed on the
Pass/Fail Report of Calibration. The allowable range for the tolerance value is
0.0 to 1000.0. If all remaining set-points on the current report require the same
tolerance value, check the Use this value for remaining set-points on this report
checkbox. Otherwise, this dialog is displayed once for each set-point on the
report.
Click the OK button to save the tolerance value. Once the tolerance value is ac-
cepted, it is permanently associated with that set-point. If a value is entered in-
correctly, refer to Section 11.2.1.2, Changing Tolerance Values, for information
on changing the tolerance values.
Click the Cancel button to close the dialog without changing the current toler-
ance value.
11.2.1.2 Changing Tolerance Values
On the Pass/Fail Report of Calibration included with MET/TEMP II, the toler-
ance values that appear on the report are manually entered by the user the first
time the report is printed. Once entered, these tolerance values are saved and
permanently associated with the respective set-points.
In case a tolerance value is entered incorrectly, MET/TEMP II provides two
methods to fix the value.

The first method forces the Tolerance dialog to be displayed every time a report
is printed and allows the tolerance values to be changed. This procedure re-
quires some basic computer knowledge. If you are unfamiliar with Windows®
INI files, you may want to find someone who is to assist with this procedure.
To force the Tolerance dialog to appear when printing a Pass/Fail Report of
Calibration:
1 Run Windows Explorer.
2 Locate and select the local hard drive and folder where MET/TEMP II
was installed (typically C:\METTEMP2).
3 In this folder, locate the METTEMP2.INI file. This file contains many
settings that dictate how MET/TEMP II operates. Double-click this file
to open it in a text editor.
4 Locate the ForceTolerance entry in the [General] section. This
entry should currently be set to False.
5 Change the word False to True as shown below, then close and save
the INI file.
6 If this entry does not exist in the [General] section, enter it now as
shown below.
Example:
[General]
ForceTolerance=True
Now, every time a Pass/Fail Report of Calibration is printed, the Tolerance dia-
log will be displayed.
Note: It is recommended that this procedure only be followed in case of a data
entry error. After correcting the error, the ForceTolerance entry should be
set back to False.
The second method is to use the Edit Test Information option in the Utilities
menu. Selecting this option displays the Edit Test Information dialog and al-
lows certain values in the MET/TEMP II database tables to be edited. It is rec-
ommended that this method be used to correct data entry errors when possible.
To use the Edit Test Information utility:
1 Select the Edit Test information option in the Utilities menu. The Edit
Test Information dialog is displayed.
2 Select the TestReadings table using the Select database table drop-down
list.
3 Locate the test number that contains the tolerance values to change. Use
the scroll bar on the right side of the grid to scroll through the records or
enter the test number in the Locate test number box.

4 Use the scroll bar at the bottom of the grid to scroll to the right until the
Misc. data column is visible. This column contains the values printed in
the Tolerance column of the Pass/Fail Report of Calibration.
5 Enter the tolerance for each set-point EXACLTY AS IT SHOULD AP-
PEAR ON THE REPORT in the Misc. data field.
6 Click the OK button to close the Edit Test Information dialog.
After the tolerance values have been changed, the Pass/Fail Report of Calibra-
tion can be printed again.

12 Performing Calibrations Using
Fixed-Points
MET/TEMP II now includes the capability of performing calibrations using
fixed-point cells. MET/TEMP II can perform calibrations using fixed-point
cells only, or fixed-point set-points can be mixed in with comparison set-points.
Important: MET/TEMP II allows calibrations to be performed using
fixed-point cells only or by mixing fixed-point set-points with comparison
set-points as a convenience to the user. It is assumed that, if you are using
these features, you are familiar with the process and theory of performing
calibrations using fixed-point cells. This User’s Guide does not provide
any detailed information as to how to perform fixed-point calibrations and
shall not be used as a substitute for proper training and source of infor-
mation on such topics. For more information on performing calibrations
using fixed-point cells, please refer to the currently available literature.
Hart periodically offers training seminars on using fixed-point cells. NIST
is also a good source of information on this topic.
12.1 Configuring Fixed-Point Cells
Before MET/TEMP II can perform calibration tests using fixed-point cells, the
fixed-point cells to use must be configured. MET/TEMP II ships with built-in
support for many fixed-point cells. Support for any fixed-point cell can be
added to MET/TEMP II at any time.

Fluke-Direct.com
To configure fixed-point cells, select the Defaults option in the File menu. The
Defaults dialog is displayed. Select the Set-points tab.
The Prompt to confirm method of realization check box indicates whether
MET/TEMP II will show a message every time a fixed-point set-point is added
to a calibration configuration indicating the current method of realization for
the selected fixed-point cell. If this check box is not selected, no prompt is
displayed.

Fixed-Points dialog is displayed.
To edit the current settings for a fixed-point cell, select the fixed-point cell from
the list and click the Edit button. The Edit Fixed-Point dialog is displayed. To
add a new fixed-point cell to MET/TEMP II, click the New button. The New
Fixed-Point dialog is displayed. To delete a fixed-point cell, select the
fixed-point cell to delete from the list and click the Delete button.
Refer to Section 3.4.2.1, Fixed-Points, for more detailed information on config-
uring fixed-point cells.
12.2 Configuring MET/TEMP II to Perform Fixed-Point
Only Calibrations
MET/TEMP II can be configured to perform calibrations using fixed-point cells
only. The only differences between configuring MET/TEMP II to perform
fixed-point only calibrations and performing comparison calibrations are in the
heat source and set-point configurations.
12.2.1 Fixed-Point Reference Readout Configuration
Even though MET/TEMP II does not actually store readings taken from a refer-
ence probe when configured for fixed-point set-points only, a reference readout
and reference probe must still be configured as if performing comparison cali-
brations. This is because Calibrate-it continuously takes readings from and
graphs the reference probe. Configure the reference readout and reference
probe as indicated in Section 4.3, Reference.
153

Fluke-Direct.com
Because MET/TEMP II must always be able to take readings from the refer-
ence, MET/TEMP II cannot be configured to use the heat sources as the
reference.
12.2.2 Fixed-Point Heat Source Configuration
To configure MET/TEMP II to perform fixed-point only calibrations, a single
heat source must be configured. Select the Heat Sources option in the Configu-
ration menu to display the Heat Source Configuration dialog.
Select the One option to indicate that a single heat source is to be used.
Select the Fixed-Points pseudo driver using the Model number drop-down list.
If the Fixed-Points option does not appear in the Model number drop-down list,
click the Drivers button to display the Install Drivers dialog and install the
Fixed-Points Pseudo driver. Click the OK button to close the Install Drivers
dialog.
When the Fixed-Points driver is selected in the Model number box, all other
controls on this dialog are disabled.

Note: The Fixed-Points Pseudo driver only needs to be configured if a calibra-
tion test does not include any comparison set-points. If a calibration test uses
one or more comparison set-points, at least one heat source must be configured
and the Fixed-Points Pseudo driver does not need to be configured.
Click the OK button to close the Heat Source Configuration dialog.
12.2.3 Fixed-Point Set-point Configuration
When MET/TEMP II has been configured with only the Fixed-Points heat
source pseudo driver as indicated in the previous section, only fixed-point
set-points can be added to the set-point configuration. Select the Set-points op-
tion in the Calibration menu to display the Set-point Configuration dialog.
The Auto-Generate Set-points and Insert Set-point buttons are always disabled.

If the Prompt to confirm method of realization check box on the Defaults dia-
log is checked, another message is displayed to confirm the currently selected
method of realization for the selected fixed-point cell. Make sure this method is
correct before continuing.
The fixed-point set-point is added to the set-points list indicating the reference
value and the current method of realization.
The Set-point, Window and Tolerance boxes on the Set-point Configuration di-
alog are disabled when a fixed-point set-point is selected. These settings cannot
be changed or do not apply for fixed-point set-points.
The Duration setting indicates the amount of soak time that MET/TEMP II
should allow once a test probe has been inserted into a fixed-point cell until
readings are taken.

12.3 Fixed-Point Calibration Process
When MET/TEMP II is configured with one or more fixed-point set-points, the
test process is slightly different than when all set-points are comparison
set-points.
For fixed-point set-points, only one test probe at a time can be inserted into the
fixed-point cell. MET/TEMP II displays a prompt to insert the first test probe
into the fixed-point cell. When the OK button on this prompt is clicked,
MET/TEMP II begins to count down the duration time for this set-point. When
the duration time has elapsed, MET/TEMP II begins to take readings from the
first test probe. The value that was entered as the Reference value for the se-
lected fixed-point cell when the cell was configured is stored as the reference
reading at that set-point. Then, MET/TEMP II prompts to insert the next test
probe into the fixed-point cell. This process is repeated for all test probes at the
current fixed-point, then for all other fixed-point set-points.
All fixed-point cells used during the calibration process are listed on the Report
of Calibration in the Test Equipment section.

13 Performing Heat Source Calibrations
MET/TEMP II was originally designed to perform comparison calibrations for
PRT, thermistor and thermocouple probes. However, MET/TEMP II has been
modified to calibrate Liquid in Glass and bi-metallic thermometers, perform
fixed-point calibrations and to calibrate some heat sources.
Since the process of calibrating a heat source is somewhat different than that of
calibrating a probe, MET/TEMP II must be setup slightly differently. This sec-
tion explains in detail the steps necessary to configure MET/TEMP II to suc-
cessfully calibrate a heat source.
13.1 Heat Source Calibration Process
MET/TEMP II can be configured to calibrate a single heat source using only a
readout device, probe and the heat source to be calibrated.
The process of calibrating a heat source is somewhat similar to calibrating a
PRT probe. The heat source is set to various set-points one at a time, allowed to
stabilize, and then readings are taken. The readings are then fed into a set of
equations to calculate new values for the calibration coefficients for the heat
source. If desired, MET/TEMP II can then write the new calibration coeffi-
cients to the heat source and take readings at additional set-points to verify the
calibration. A custom report for heat source calibrations is included with
MET/TEMP II and can be used to print the results of the calibration.
The readings that MET/TEMP II takes consist of temperature readings from the
reference probe and set-point resistance readings from the heat source. The
set-point resistance readings are not actually resistance measurements, but re-
sistance values that are calculated by the heat source based on the current
set-point temperature and the heat source’s current calibration coefficients.
Note: Because not all heat sources supported by MET/TEMP II have a com-
mand to read set-point resistance values, not all heat sources can be calibrated
by MET/TEMP II. By the same token, even heat source models that can be cal-
ibrated by MET/TEMP II may require a firmware upgrade to support the
set-point resistance command.
13.2 Configuring MET/TEMP II to Perform Heat
Source Calibrations
The following sections describe in detail the steps that must be followed to con-
figure MET/TEMP II to perform a heat source calibration. Because
MET/TEMP II was originally intended to calibrate probes, not all of the config-
uration steps are obvious or intuitive. Please read the following sections care-
fully and be sure you understand this process before attempting to calibrate a
heat source.

Figure 80 shows one possible instrument configuration for performing a heat
source calibration. When configuring a heat source calibration, you may use
the Equipment Info dialog to gain quick access to the various configuration
dialogs or you may select the appropriate options from the Configuration and
Calibration menus. Before beginning, select the New option from the File menu
to clear any current configuration information.
13.2.1 Default Settings
Before configuring MET/TEMP II to calibrate a heat source, there are some
settings that need to be checked that will affect the calibration process. The fol-
lowing sections describe these settings.
13.2.1.1 Writing New Coefficients To Heat Source
MET/TEMP II has a default setting that determines whether the new calculated
values of the calibration coefficients should be written to the heat source. This
setting must be configured prior to starting the heat source calibration test. Se-

lect the Defaults option from the File menu to display the Defaults dialog. Se-
lect the Test tab.
The Write new coefficients to heat source after calibration check box deter-
mines whether MET/TEMP II will attempt to write the new calculated values
for the calibration coefficients to the heat source prior to taking readings at the
As Left set-points.
If this option is selected, MET/TEMP II attempts to write the new coefficient
values to the heat source and verify that the heat source accepted the new val-
ues before proceeding to take readings at the As Left set-points.
If this option is not selected, MET/TEMP II will not attempt to write the new
coefficient values to the heat source. If there are any As Left set-points config-
ured, readings will be taken at these set-points using the same calibration coef-
ficients that were in the heat source when the As Found readings were taken.
It is recommended that this option always be selected if As Left set-points are
configured.

tion is to configure the scanner. Click the Scanner button on the Equipment
Info dialog or select the Scanner option from the Configuration menu. The
Scanner Configuration dialog is displayed.
When calibrating a heat source, MET/TEMP II actually uses the scanner as if it
was the reference readout and the test probe is if it was the reference probe. Se-
lect the instrument to use as the scanner. If the selected instrument requires the
use of modules or a multiplexer, click the Modules button to configure the
modules or multiplexer. Refer to Section 4.4.1, Scanner Configuration Dialog,
for more information on configuring the scanner.
Click the OK button to close the Scanner Configuration dialog.
13.2.5 Configure Test Probes
The fourth step to configuring MET/TEMP II to perform a heat source calibra-
tion is to configure the test probe. Click the Test Probes button on the Equip-
ment Info dialog or select the Test Probes option from the Calibration menu.

When calibrating a heat source, MET/TEMP II actually uses the test probe as if
it was the reference probe. MET/TEMP II only allows a single test probe to be
configured. If more than one test probe is configured, MET/TEMP II will not
allow a heat source calibration test to start!
Select the model of the test probe (reference probe) to use to calibrate the heat
source. Fill in the serial number, probe type, report units, manufacturer, de-
scription and current/CJC boxes. Note that the report units are limited to C and
F.
Next, select the calibration and recalibration dates for the test probe (reference
probe).
When the MET/TRACK link is active, the MT Asset number box is displayed.
This box indicates the asset number that is assigned to this probe. An inven-
tory record must exist in the MET/TRACK database for this probe before
MET/TEMP II can use it to perform calibrations! A current calibration
record must also exist in the MET/TRACK database. MET/TEMP II will
automatically attempt to locate the records in the MET/TRACK database when
the model, serial number and manufacturer information have been entered. If
the asset number is found, MET/TEMP II displays the asset number in the MT
Asset number box. Depending on the settings on the MET/TRACK tab of the
Defaults dialog, the description, calibration and recalibration dates may be syn-
chronized with the information in the MET/TRACK database. If the asset can-
not be found in the MET/TRACK database, a message is displayed. Click Yes
tolaunchMET/TRACKtocreateormodifyassetrecordsorclickNotoeditthe
information in MET/TEMP II.
Important: When MET/TEMP II attempts to locate an asset in the
MET/TRACK database, the model, serial number and manufacturer infor-
mation must be an EXACT (case-insensitive) match! If the manufacturer
information in MET/TEMP II does not match the manufacturer informa-
tion in MET/TRACK, you may need to modify the manufacturer informa-
tion in the MET/TRACK inventory record in order for MET/TEMP II to
locate it. Where applicable, you may be able to modify the manufacturer
information in MET/TEMP II.
Note: Since the test probe is being used as if it was the reference, make sure
the calibration coefficients for the test probe have been entered into the ther-
mometer readout and the temperature readings are accurate before starting the
heat source calibration test.
Click the OK button to close the Test Probe Configuration dialog.
13.2.6 Configure Heat Source

When the MET/TRACK link is active, the MT Asset number box is displayed.
This box indicates the asset number that is assigned to this heat source. An in-
ventory record must exist in the MET/TRACK database for this heat
source before MET/TEMP II can calibrate it! MET/TEMP II will automati-
cally attempt to locate the records in the MET/TRACK database when the
model, serial number and manufacturer information have been entered. If the
asset number is found, MET/TEMP II displays the asset number in the MT As-
set number box. Depending on the settings on the MET/TRACK tab of the De-
faults dialog, the description may be synchronized with the information in the
MET/TRACK database. If the asset cannot be found in the MET/TRACK data-
base, a message is displayed. Click Yes to launch MET/TRACK to create or
modify asset records or click No to edit the information in MET/TEMP II.
Note: When MET/TEMP II attempts to locate an asset in the MET/TRACK da-
tabase, the model, serial number and manufacturer information must be an EX-
ACT (case-insensitive) match! If the manufacturer information in MET/TEMP
II does not match the manufacturer information in MET/TRACK, you may
need to modify the manufacturer information in the MET/TRACK inventory re-
cord in order for MET/TEMP II to locate it. Where applicable, you may be able
to modify the manufacturer information in MET/TEMP II.
Note: MET/TEMP II cannot calibrate all of the heat source models.
MET/TEMP II performs a check when the OK button is clicked to ensure that
MET/TEMP II supports calibrating the selected heat source model. If the se-
lected heat source model cannot be calibrated, a message is displayed at this
time.
To determine if a particular heat source can be calibrated, click the Test Cali-
bration Compatibility button. MET/TEMP II will attempt to determine if the
connected heat source responds to the commands that are required to success-
fully calibrate the heat source. If the heat source does not respond to the com-
mands, an error message is displayed. Otherwise, a message is displayed
indicating the heat source responded successfully to the commands.
Clicking the Customer button displays the Customer Information dialog for en-
tering more information about the heat source being calibrated.
Click the OK button to close the Heat Source Configuration dialog.
13.2.7 Configure Set-points
The last step to configuring MET/TEMP II to perform a heat source calibration
is to configure the set-points to use to calibrate the heat source. Click the
167

Fluke-Direct.com
Set-points button on the Equipment Info dialog or select the Set-points option
from the Calibration menu. The Set-point Configuration dialog is displayed.
When calibrating a heat source, all of the controls on this dialog are initially
disabled. A heat source set-point configuration file must be opened to configure
the initial set-points to use to perform the heat source calibration.
Note: Fixed-point set-points cannot be used when calibrating a heat source.
The Insert Fixed-Point button is always disabled. Also, set-points cannot be
auto-generated. The Auto-Generate Set-Points button is also disabled. The Re-
move All Set-points button is always disabled.
Click the Open button to open a set-point configuration file. MET/TEMP II
ships with one default set-point configuration file (in degrees C) for each heat
source model that MET/TEMP II can calibrate. These set-point configuration
files are installed to the \METTEMP2\CONFIG\CALFILES folder. Select the
appropriate set-point configuration file. Click the OK button to open the se-
lected file. The default set-points are read in and listed in the set-points list.

Important: The default set-point configuration files are installed as
Read-Only files. If you wish to modify the set-points used to calibrate a
heat source, open the default set-point configuration file for that heat
source model, make the necessary changes and save the configuration to a
new configuration file using a different name.
Once the set-point configuration file has been opened, each set-point in the
set-point list is labeled as either an As Found or As Left set-point.
As Found set-points are the set-points at which readings will be taken to calcu-
late the new calibration coefficients for the heat source. Depending on the se-
lected heat source, up to four As Found set-points will be required. As Found
set-points cannot be moved or removed from the set-point list. The Insert
Set-point and Remove Set-point buttons are always disabled when an As Found
set-point is selected. The value of each As Found set-point, however, can be
changed to a new value.
As Left set-points are optional can be moved and/or removed as desired. To in-
sert a new As Left set-point, click the Insert Set-point button. To remove the
currently selected As Left set-point, click the Remove Set-point button.
The Set-point, Window, Tolerance, Duration and Uncertainty settings for any
set-point can be changed as desired.
The Window, Tolerance and Duration settings are used in the same manner as
when performing comparison calibrations. Refer to Section 5.1.1, Set-point
Configuration Dialog, for more details.
When setting the Window and Tolerance, keep in mind the resolution of the
readings on the display of the heat source (i.e. do not attempt to set the Window
or Tolerance to 0.010 if the resolution on the display of the heat source being
calibrated is only 0.1).
When setting the Duration, be sure to allow plenty of time for the heat source
to soak at the set-point temperature. A minimum of 20 to 30 minutes is sug-
gested for most heat sources.
When performing a heat source calibration, the Uncertainty is used to deter-
mine the pass/fail status. This value should be set to the heat source’s accuracy
specification at each set-point. This value will print in the Tolerance column on
the Heat Source Report of Calibration.
Note: The values for the Window, Tolerance and Duration in the default
set-point configuration files are suggested settings only! There is no guar-
antee that these default settings will work perfectly in every case. You may
need to modify these settings and create your own set-point configuration
files to meet the specific needs of your heat sources.

Note: When calibrating a micro-bath, you also need to be aware of the
temperature range of the calibration and the fluid being used in the mi-
cro-bath. Be sure to use a fluid that covers the entire range of the calibra-
tion or limit the calibration to the range of the fluid being used!
If you changed any of the set-point configuration settings and you wish to use
the current settings again, click the Save As button to save the current set-point
configuration to a new configuration file.
Click the OK button to close the Set-point Configuration dialog.

Finish configuring the test information on this dialog for the heat source cali-
bration. Refer to Section 5.5.2, Test Information Dialog for more details.
Note: When selecting the resolution setting for the readings, it is recommended
that a setting of 3 decimal places or more be used. The set-point resistance
readings from the heat source are typically formatted to 3 decimal places.
Using less resolution will most likely decrease the quality of the calibration.
Click the OK button to close this dialog and start the calibration test.
13.3 Performing Heat Source Calibrations
Heat source calibrations are performed in a similar manner to comparison cali-
brations. MET/TEMP II sets the heat source to the first set-point, waits until the
display of the heat source reaches the set-point and stabilizes, counts down the
duration time and takes readings. This process is repeated for all configured As
Found set-points.
Since MET/TEMP II must be configured to use the heat source as the reference
to perform heat source calibrations, the graph and display show the current heat
source temperature as indicated on the heat source’s display.
When MET/TEMP II takes the readings, the readings that are taken from the
test probe (in temperature) are stored in the database as the reference readings.
MET/TEMP II then takes set-point resistance readings from the heat source and
stores them in the database as the UUT readings.
After MET/TEMP II has taken readings at all As Found set-points, new calibra-
tion coefficients are calculated and stored in a database. If the Write new coeffi-
cients to heat source after calibration check box on the General tab on the
Defaults dialog is selected, MET/TEMP II attempts to write the new coefficient
values to the heat source. These coefficients are then verified to make sure the
heat source accepted the new values. If the value read from the heat source for
a coefficient does not match the calculated value, a message is displayed indi-
cating the calculated value and the value read from the heat source. Typically,
this message indicates that the calculated value of the coefficient exceeded the
acceptable range of values for that coefficient.
If one or more As Left set-points were configured, MET/TEMP II then pro-
ceeds to take readings at each of the As Left set-points in the same manner out-
lined above until readings have been taken at all set-points.
13.4 Printing Heat Source Reports of Calibration

14 MET/TRACK Export Process
MET/TEMP II can export calibration data to the MET/TRACK database when
the link to MET/TRACK is active. For more details on activating the link to
MET/TRACK, refer to Section 3.4.9, MET/TRACK Tab.
The first step to exporting calibration data to MET/TRACK is to identify the
data to export. Click the Export Calibration Data to MET/TRACK option in the
Utilities menu. Select the test containing the data to export and click the Export
button. The calibration data for ALL instruments calibrated are exported to
MET/TRACK.
When a calibration test is closed, MET/TEMP II can be configured to either au-
tomatically export calibration data or to prompt to export the calibration data. If
characterization coefficients need to be calculated for a probe, the coefficients
must be calculated before exporting the calibration data to MET/TRACK.
MET/TEMP II creates a calibration record for each UUT and exports the fol-
lowing information to the MET/TRACK database:

During the export process, if no asset number was previously assigned to the
UUT or test equipment, the Locate MET/TRACK Asset dialog is displayed.
This dialog allows the user to view the model, serial number and manufacturer
of the instrument. If a matching record cannot be located in the MET/TRACK
database, this gives the user the opportunity to add a record for the instrument
in MET/TRACK or to modify the information in either MET/TRACK or
MET/TEMP II so that the asset number can be found and assigned to the in-
strument.
This dialog will typically appear for any of the following reasons:
• The calibration was performed with a previous version of MET/TEMP II
(Calibrate-it)
• The link to MET/TRACK was not active when the calibration was per-
formed
• The asset record for the UUT or test equipment cannot be located in the
MET/TRACK database
♦
The record has not been created yet
♦
The record existed at one time, but has been deleted
♦
The model, serial number and manufacturer do not match EXACLTY

Important: When MET/TEMP II attempts to locate an asset in the
MET/TRACK database, the model, serial number and manufacturer must
match EXACTLY! If an asset record exists but MET/TEMP II is unable to
locate it, you may need to modify the manufacturer information in the
MET/TRACK database.
When exporting temperature vs. temperature calibration data, the Tolerances
dialog is displayed if this data is being exported for the first time and the appro-
priate option on the MET/TRACK tab of the Defaults dialog is selected. Enter
the tolerances for each set-point for each UUT to allow MET/TEMP II to auto-
matically determine the setting for the Pass field in the calibration summary
record.
When the export process is complete, a success message is displayed. If any er-
rors occurred during the export process, one or more error messages may be
displayed. To assist Technical Support in determining the cause of the error,
please write down the exact wording of any error message you receive. Refer to

ported again.
Enter the tolerance value at each set-point for the indicated asset. The tolerance
values are formatted automatically to the same number of decimal places as the
values in the UUT column when the cursor leaves each cell.
When the calibration data is exported, MET/TEMP II compares the absolute
value of the Error to the absolute value of the Tolerance. If the value of the Er-
ror is greater than the value of the Tolerance, at any set-point, the Pass field in
the calibration summary record is set to “N”. If the Error is less than or equal to
the Tolerance for all set-points, the Pass field is set to “Y”.
Click the OK button to export the calibration data for this asset to the

14.2 Changing Coefficients Export Field
By default, the characterization coefficients for a probe and the heat source cal-
ibration constants are exported to the 2341 field of the calibration summary re-
cord when exported to MET/TRACK. However, this field can be changed by
following the process outlined below.
1 Using a text editor, locate and open the MT32MTII.INI file. This file is
located in the C:\WINDOWS (for Windows® 9x/ME/XP) or C:\WINNT
(for Windows® 2000/NT) folder.
2 Locate the [Mapping] section. There should be one entry in this
section:
[Mapping]
CoefficientsField=2341
3 Change the field referenced by the CoefficientsField entry to the
field the coefficients should be written to.
[Mapping]
CoefficientsField=2354
4 Save and close the file.
The next time coefficients are exported to the MET/TRACK database, any
probe coefficients or heat source constants should be written to the referenced
field.
Important: MET/TEMP II does not attempt to validate the field type or
length! Be sure to map the coefficients to a field of type SPVAL with
enough characters to hold the type of coefficients or constants being writ-
ten to it or the export process may fail!

15 Coefficients and Tables Application
15.1 What is the Coefficients and Tables Application?
The Coefficients and Tables application (formerly known as Generate-it)isan
add-on for MET/TEMP II (formerly Calibrate-it). MET/TEMP II is designed to
acquire and store data from reference probes and test probes (UUTs). This data
is used by this software to calculate characterization coefficients, print Reports
of Calibration, and generate tables.
This software calculates characterization coefficients for platinum, thermistor,
and thermocouple probes. The types of coefficients that can be calculated are:
ITS-90 for platinum probes; IPTS-68 for platinum probes; Callendar-Van
Dusen for platinum probes; Polynomial for platinum and thermistor probes;
and coefficients for thermocouple probes types B, E, J, K, N, R, S, T, and AuPt.
This software also generates temperature vs. resistance, temperature vs. ratio,
and temperature vs. EMF tables.
This software also allows data that was acquired during a test as well as calcu-
lated coefficients to be exported to an ASCII text file. This data can then be
easily imported into a spreadsheet or other application.
15.2 New Features
15.2.1 Version 4.1
A list of new features and enhancements in version 4.1 of the Coefficients and
Tables application follows:

15.5 Calculating Characterization Coefficients
This software was designed to take the test data acquired by MET/TEMP II and
calculate characterization coefficients. The software can then use these coeffi-
cients to generate temperature vs. resistance, temperature vs. ratio or tempera-
ture vs. EMF tables.
Before the Coefficients and Tables application can be used, you must first per-
form a calibration test using MET/TEMP II. When performing a calibration
test, keep in mind the following:
• The readings for the reference probe MUST be in a temperature scale (C,
F or K)
• The readings for the test probes (UUTs) MUST be in either resistance
(Ohms or kOhms) or voltage (mV or µV)
• MET/TEMP II MUST acquire readings at a sufficient number of
set-points, depending on the type of coefficients that are to be calculated
(refer to Section 15.12, Requirements and Methods, for more details)
The following sections describe in detail how to calculate characterization coef-
ficients and print Reports of Calibration and tables.
15.5.1 Calculating Coefficients
Prior to calibrating the UUT using MET/TEMP II, you should decide what type
of characterization coefficients you want to calculate. The set-points you select
depend on the type of characterization you choose.
After a test probe (UUT) has been calibrated using MET/TEMP II, this soft-
ware can be used to calculate characterization coefficients. Launch the applica-
tion from the Utilities menu in MET/TEMP II.

The following sections describe how to calculate coefficients for PRT/RTD,
Thermistor and Thermocouple probes.
15.5.1.1 Calculating PRT/RTD Coefficients
To calculate coefficients for PRT/RTD probes, select the Platinum Probe option
in the Coefficients menu. The Platinum Probe Coefficients dialog is displayed.
Select the type of coefficients to calculate using the Type of coefficients to cal-
culate drop-down list. For PRT/RTD probes, the choices are:
• ITS-90
• IPTS-68
• Callendar-Van Dusen
• Polynomial
Depending on the type of coefficients selected, additional information may or
may not be required.
If ITS-90 is selected, the low range and high range options must be chosen us-
ing the Low range and High range drop-down lists. ITS-90 coefficients can be
calculated for the following subranges:
Low Range
• None
• Range 4 (83.8058 K to 273.1600 K)
• Range 5 (234.3156 K to 302.9146 K)
High Range
• None
• Range 6 (273.1500 K to 1234.9300 K)

• Range 7 (273.1500 K to 933.4730 K)
• Range 8 (273.1500 K to 692.6770 K)
• Range 9 (273.1500 K to 505.0780 K)
• Range 10 (273.1500 K to 429.7485 K)
• Range 11 (273.1500 K to 302.9146 K)
Note: The temperature ranges indicated are displayed in Kelvin and are
intended for convenience only.
If Polynomial is selected, the order of the polynomial must be selected using
the Order drop-down list. This application can calculate from 3rd to 9th order
polynomials for PRT/RTD probes.
Note: The number of coefficients calculated is always one more than the
order of the polynomial (i.e. for a 4th order polynomial, 5 coefficients are
calculated). The minimum number of set-points required must exceed the
order of the polynomial by at least 1.
If IPTS-68 or Callendar-Van Dusen is selected, no additional settings are
required.
Click the OK button to continue and display the Calculate Coefficients dialog
(refer to Section 15.5.1.4, Calculate Coefficients Dialog).

15.5.1.2 Calculating Thermistor Coefficients
To calculate coefficients for Thermistor probes, select the Thermistor Probe op-
tion in the Coefficients menu. The Thermistor Probe Coefficients dialog is dis-
played.
Select the type of coefficients to calculate using the Type of coefficients to cal-
culate drop-down list. For Thermistor probes, the only choice is Polynomial.
Both T(R) and R(T) polynomial coefficients are calculated.
The order of the polynomial must be selected using the Order drop-down list.
The application can calculate from 3rd to 6th order polynomials for Thermistor
probes.
Note: The number of coefficients calculated is always one more than the
order of the polynomial (i.e. for a 3rd order polynomial, 4 coefficients are
calculated). The minimum number of set-points required must exceed the
order of the polynomial by at least 1.
Select whether or not the Steinhart-Hart method should be used. The coeffi-
cients are calculated by checking or unchecking the Steinhart-Hart check box.
When this option is selected, the third coefficient (squared term) is set to 0.0.
Refer to Section 15.12.4, Polynomial Requirements, for more information
about the Steinhart-Hart method.

Important: The accepted thermistor model is based upon the logarithmic
resistance-temperature characteristic in terms of absolute temperature
(Kelvin). The accuracy of a model based upon degrees F or degrees C has
not been tested. Therefore, this application always calculates polynomial
coefficients for thermistor probes using Kelvin. If reference readings are in
degrees F or degrees C, the readings are automatically converted to Kel-
vin values before the fit is computed.

• Type T Thermocouple
• Type AuPt Thermocouple
Next, select the temperature range that your UUT was calibrated over using the
Temperature range drop-down list. The available choices depends on the type
of thermocouple selected above.
Note: The temperature ranges for thermocouple probes are always dis-
played here in degrees C and are intended for convenience only.
Select the appropriate option for cold junction readings using the Cold junction
compensation setting drop-down list. MET/TEMP II can be configured to take
CJC readings for thermocouple probes. This application needs to know the
scale of those readings. If CJC readings are not required or were not taken, se-
lect the Do not use CJC in calculations option. The CJC readings are ignored. If
you select any other option, the test probe readings are compensated according
to the CJC readings for each set-point before calculating the coefficients.
Note: For all Hart thermometer readouts, cold junction readings are AL-
WAYS in degrees C! If cold junction readings were entered manually for
your UUT, select the appropriate option.

When calculating Polynomial coefficients for Platinum probes, the Select Cal-
culation Scale dialog is displayed.
Some instruments that use Polynomial coefficients require the coefficients to be
calculated using a specific temperature scale. The software allows the user to
select the temperature scale to use:
• If the reference readings are in degrees C, the user may select between C
and K.
• If the reference readings are in degrees F, the user may select between F
and K.
• If the reference readings are in K, coefficients will automatically be calcu-
lated using K.
Many readout instruments that accept Polynomial coefficients require that the
coefficients be calculated using reference readings in a particular temperature
scale. This feature allows reference readings to be used as acquired by
MET/TEMP II (with no conversion) or to be converted automatically to K by
the application.
Note: This application does not provide the option of converting reference
readings from degrees F to degrees C nor vice-versa. Also, if reference
readings were acquired in K, the Select Calculation Scale dialog will not
be displayed and Polynomial coefficients will automatically be calculated
using K.

15.6 Exporting Data and Coefficients
The software has a feature that allows the test data acquired by MET/TEMP II
to be exported to a text file. Also, the characterization coefficients can be ex-
ported to a text file.
The following sections describe in detail how to export data.
15.6.1 Export Data
The software has a feature that allows the test data acquired by MET/TEMP II
to be exported to a text file. This can be useful if you have analysis software
that you want to use to analyze, graph, or manipulate the acquired test data.
To export test data, select the Export Data option in the File menu or click the
Export Data button on the toolbar. The Export Data dialog is displayed.
The Export Data dialog allows the user to specify a date range using the Start-
ing date and Ending date drop-down calendars. These dates are used to filter
the list of tests displayed in the Select tests list. The last used ending date is re-
membered every time data is exported and becomes the starting date the next
time this dialog is displayed. The ending date defaults to the current date.
Therefore, the list of tests in the Select tests list should default to all tests since
the last export was performed.

To change the starting and/or ending dates, use the drop-down calendars to se-
lect new dates. The tests listed will update automatically.
Select the delimiter to use when exporting the data using the Export delimiter
drop-down list. The software supports using either a Tab or Comma (,) as the
delimiter.
Note: The software recognizes and uses the International/Regional settings
such as the date, time, and number formats as set in the Windows® Control
Panel’s Regional Settings or International icon. If a comma (,) is being used as
the decimal separator, the Tab option must be selected as the export delimiter in
order for the data to be properly imported into other software. A warning mes-
sage is displayed when the Export button is clicked.
If you wish to export only data for test probes that were marked as check stan-
dards in MET/TEMP II, select the Export only Check Standard data from se-
lected tests check box.
Select the test to export by clicking on the appropriate row in the Select tests
list.
To export the test data for the selected test(s), click the Export button. A

15.6.2 Customizing Export Data
The software has a feature that allows the user to define the data to be exported.
This feature is accessible by clicking the Configure button on the Export Data
dialog. Clicking this button displays the Configure Export Fields dialog.
The export file created can be divided up into three sections: header, test equip-
ment and test readings. These three sections are represented on this dialog by
the three list boxes entitled: Header fields to export, Equipment fields to export
and Readings fields to export.
The first section of the export file is called the header section. The header sec-
tion generally consists of general test information that applies to all test probes
(UUTs) and all readings taken for that test. When the export file is created, a
one line header section is written to the file for each of the selected tests to
export.
The next section is called the equipment section. The equipment section gener-
ally consists of one record for every piece of test equipment used to perform
the calibration test. When the export file is created, a one line entry is written to
the file for each piece of test equipment used to perform the calibration test.
The last section is called the readings section. The readings section generally
consists of the test probe (UUT) information and the actual readings taken.
When the export file is created, a one line entry is written to the file for each
reading for each test probe (UUT). If the data to be exported contains multiple
211

UUTs, the first UUT’s data is written followed immediately by the second
UUT’s readings, etc.
Each of the sections is separated by a blank line. If multiple tests are being ex-
ported to the same export file, each test’s data is separated by two blank lines.
If no fields have been defined to export to a section of the export file, that sec-
tion is simply skipped.
An example of an export data file is shown below:
When MET/TEMP II is installed, the header and test equipment sections are
blank, and the readings section is configured so that the exported data is com-
patible with previous versions of this software.
To customize the data to be exported in each section, select the table containing
the data to be exported using the Select table drop-down list. Available tables
are:
• TestStart - Contains general test data that applies to all UUTs such as test
number, ambient conditions, paragraph, test procedure, technician name,
etc.
• TestEquipment - Contains information about the test equipment used to
perform the calibration test such as model and serial numbers, calibration
& recall dates, etc.
• TestProbeEquipment - Contains information about each of the test
probes (UUTs) that were calibrated such as model and serial numbers,
scale of readings, etc.

Fluke-Direct.com
• TestReadings - Contains all of the readings for all test probes (UUTs) in-
cluding set-points, reference readings, test probe readings, CJC readings,
uncertainty values, method of realization, etc.
Next, select the field to be exported in the Select field list. Then click the
button below the section list to which the field should be added. The field is
added to the end of the list.
The order in which the fields appear in the lists is the order that the fields will
be exported. To move a field up or down in a list, select the field to move, then
click the or button accordingly.
To remove a field from a list, select the field and click the button.
Any field may be added to any of the sections. Also, any field can be added to a
single list as many times as needed. However, use caution when adding fields.
Be aware that:
• There is only one record in the TestStart table for each test. Adding a
field to a section from the TestStart table causes the same value to be
written every time.
• There are multiple records in the TestEquipment, TestProbeEquipment
and TestReadings records for each test. Adding a TestEquipment field
to the header section, for example, will only export that field’s value for
the first record in the TestEquipment table for this test.
The information about the fields to export to each section of the export file is
saved in the EXPORT.INI file which is located in the C:\METTEMP2 folder
(or the folder where MET/TEMP II was installed). A second file containing an
alternate export definition was installed when MET/TEMP II was installed.
This file is named EXPORT.INX and is also installed in the folder where
MET/TEMP II was installed. This file can be used as a starting point for creat-
ing your own export definition. To use this file, simply rename the current EX-
PORT.INI file to something else, and rename the EXPORT.INX file to
EXPORT.INI. The next time the Configure Export Fields dialog is displayed,
this file’s definition is read in and displayed.
Important: Never attempt to manually edit the EXPORT.INI file! This file
needs to be accurate for the export feature to function properly. Always
use the Configure Export Fields dialog to make changes to the export data
configuration.
Click the OK button to save the new export data configuration and close this di-
alog. Clicking the Cancel button closes this dialog without saving changes.

15.9.3.1 Maintain Test Results Dialog
The Maintain Test Results dialog can be used to determine the validity of test
probe data and to remove data from the database.
Note: This feature does NOT determine the validity of coefficients calcu-
lated by the software. It determines only if a test probe is valid based on
the presence or absence of information for the test in the database.
To validate or remove test probes from the database, select the test probes from
the Select probes list and click the Validate or Remove button. To validate or
remove all test probes, click the Validate All or Remove All button respectively.
Test probe validation is explained in the following section.
Important: Use caution when removing test probes. Once a test probe has
been removed, the software will not be able to print Reports of Calibration
or tables for that test probe! All coefficient data is deleted permanently.
For this reason, the user must confirm removing records from the data-
base.
15.9.3.2 Test Probe Validation
Results of coefficient calculations are stored in a table in the database. Other in-
formation required to print a Report of Calibration for the test probes is stored
in many separate tables within MET/TEMP II’s database in a relational manner.

print a Report of Calibration for a test probe using this application. If the data-
base became corrupt, some of the data for a particular test probe may have been
lost. These are a couple of the reasons why test probe data may not be valid.
The validation feature can be used to determine if there are records for every
test in every required table.
Clicking the Validate or Validate All buttons on the Maintain Test Results dia-
log performs a check on the selected test probes to see if the required informa-
tion to print a Report of Calibration exists in each of the database tables for the
test probe. If the software determines that required records are missing (a test
probe is invalid), the Invalid Test Probe dialog is displayed. Otherwise, a mes-
sage appears stating the validity of the test probes.
The Invalid Test Probe dialog displays information about the test probe that is
being validated. The Report number is invalid for the following reasons list at
the top of the dialog shows the reasons why the test probe is considered to be
invalid.
Based on the information provided, the user must decide what to do with the
test. The options available to the user are to not remove or to remove the se-
lected test probes. Selecting the Do not remove report option leaves the test
probe as is. Selecting the Remove this report option permanently removes the
test probe coefficients data from the database. Information about the test, test
equipment, and test readings cannot be removed.

15.11 Reports of Calibration and Tables
This section describes in detail the default Report of Calibration and table that
are built into this application.
15.11.1 Default Report of Calibration
The default Report of Calibration was designed to meet the ANSI/NCSL
Z540-1 specification.
The default Report of Calibration contains: the report number, the test probe in-
formation, calibration range, received condition, excitation current used (if ap-
plicable), test procedure, customer name and address, calibration test paragraph
and notes, the actual data used to calculate coefficients, the characterization co-
efficients, a list of the test equipment, calibration date, recall date, ambient tem-
perature and humidity, customer order ID, technician name, and a place for
technician and approval signatures. The actual data consists of the actual values
(reference readings), UUT values (test probe readings), the calculated residuals
and method of realization.
The fonts, sizes, and styles used on the default Report of Calibration can be
changed on the Fonts & Sizes tab of the Defaults dialog.
The top, bottom, left, and right margins and the column widths for the Test
Equipment table on the Report of Calibration can be set using the appropriate

logo can also be added to the upper left corner of the Report of Calibration us-
ing the settings on this tab.
Reports of Calibration can be saved to a report file from the Print Preview win-
dow and opened, viewed and printed by selecting the Recall Saved Report/Ta-
ble option from the File menu or by running the Report Viewer utility. See
Section 17, Report Viewer Utility, for more details.
The report number is printed on each page of the Report of Calibration. The re-
port number is a unique number consisting of the test number and the scanner
channel to which the test probe was connected. These two pieces of informa-
tion are concatenated together with a dash.
The test probe information consists of the test probe model number, serial num-
ber and description. This information is printed at the top of the first page along
with the calibration range, received condition, excitation current used, and test
procedure number.
The paragraph text follows the test probe information.
The raw data section contains the readings taken by MET/TEMP II that were
used to calculate the coefficients and the resulting residuals.
Note: The Method of Realization column prints only if the test was performed
using MET/TEMP II v4.0 or later.
The coefficients print immediately below the raw data section.
The Test Equipment section lists each of the instruments that was used to per-
form the calibration. Each instrument’s manufacturer, model, description, serial
number and recall date is indicated. For instruments that do not require calibra-
tion, NCR is printed in the Recall Date column.
The notes text follows the coefficients.
The recall date is the date the test probe or test equipment is due for
recalibration. Recall date is synonymous with recalibration date.
Note: If the calibration interval was set to 0, the recall date is omitted from the
Report of Calibration for that test probe.
The technician is the name of the person who performed the test.
To see an example of the default Report of Calibration, see Figure 132.
15.11.2 Default Table
The default table includes: the date, table title, report number and pagination
information on the top of every page. Pages of the table are automatically num-
bered. If a Report of Calibration is being generated and printed with the table,
the page numbering is continuous (i.e. the Report of Calibration pages are num-
bered1toi where i is the number of pages in the Report of Calibration and the
table pages are numbered i + 1 to n where n is the sum of the number of pages
in the Report of Calibration and the table).

If the table is being printed by itself, the pages are numbered starting with the
starting page number specified on the Other Settings tab of the Table Options
dialog.
The table is formatted into three columns. Each row in each column consists of
up to 3 sets of data, depending on the selected options. The first set of data is
the temperature value. The second set is the resistance, ratio or EMF value, de-
pending on the type of table being generated. The third column is the first de-
rivative, inverse difference or error value, depending on the type of table being
generated.
The table’s minimum and maximum temperatures, temperature scale and the
increment (step) between each temperature value is set on the Type and Range
tab of the Table Options dialog.
To see an example of the default table, refer to Figure 133.
15.12 Requirements and Methods
The following sections describe in detail the requirements for calculating char-
acterization coefficients and the methods used to perform the calculations.
15.12.1 ITS-90 Requirements
The following requirements must be met when ITS-90 is selected as the type of
coefficients to calculate for platinum probes. For more information concerning
the method used to calculate the ITS-90 coefficients, refer to Section 15.12.6,
Methods Used for Calculating Coefficients.
1. The reference probe readings must be in temperature (C, F or K).
2. The UUT (test probe) readings must be in resistance (Ohms or kOhms).
3. At least 2 set-points must be used, but no more than 21 set-points can be
used. The actual minimum and maximum number of set-points that can
be used depends on the selected low range and high range.
4. There must be one set-point within a few degrees of the Triple-Point of
Water (TPW = 0.01C) (preferably as close to it as possible).
5. Low range criteria:
a. The following low ranges can be selected
i. None
ii. Range 4 (83.8058 K to 273.16 K)
iii. Range 5 (234.3156 K to 302.9146 K)
b. Both ranges 4 and 5 require the Triple-Point of Water (TPW) set-point
and at least 2 and no more than 10 additional set-points.
c. All set-points should fall within the temperature range of the selected
low range.

6. High range criteria:
a. The following high ranges can be selected
i. None
ii. Range 6 (273.15 K to 1234.93 K)
iii. Range 7 (273.15 K to 933.473 K)
iv. Range 8 (273.15 K to 4692.677 K)
v. Range 9 (273.15 K to 505.078 K)
vi. Range 10 (273.15 K to 429.7485 K)
vii. Range 11 (273.15 K to 302.9146 K)
b All Ranges require the Triple-Point of Water (TPW) set-point and the
following:
i. Range 6 requires at least 4 and no more than 10 set-points.
ii. Range 7 requires at least 3 and no more than 10 set-points.
iii. Ranges 8 and 9 require at least, 2 but no more than 10 set-points.
iv. Ranges 10 and 11 require at least 1 but no more than 10 set-points.
c. All set-points should fall within the temperature range of the selected
high range.
7. Selecting None for both the low range and the high range is not
permitted.
8. The residuals are calculated for each set-point used in calculating the co-
efficients with the exception of the Triple-Point of Water (TPW)
set-point. Residuals are always in the same scale as the reference probe
readings.
15.12.2 IPTS-68 Requirements
The following requirements must be met when IPTS-68 is selected as the type
of coefficients to calculate for platinum probes. For more information concern-
ing the method used to calculate the IPTS-68 coefficients, refer to Section
15.12.6, Methods Used for Calculating Coefficients.
1. The reference probe readings must be in temperature (C, F or K).
2. The UUT (test probe) readings must be in resistance (Ohms or kOhms).
3. Exactly 4 set-points must be used:
a. One set-point must be within a few degrees of 0C (32F or 273.15 K)
(preferably as close to 0C as possible).
b. One set-point must be below 0C.
c. Two set-points must be above 0C.

4. The residuals are not calculated when calculating IPTS-68 coefficients.
15.12.3 Callendar-Van Dusen Requirements
The following requirements must be met when Callendar-Van Dusen is selected
as the type of coefficients to calculate for platinum probes. For more informa-
tion concerning the method used to calculate the Callendar-Van Dusen coeffi-
cients, refer to Section 15.12.6, Methods Used for Calculating Coefficients.
1. The reference probe readings must be in temperature (C, F or K).
2. The UUT (test probe) readings must be in resistance (Ohms or kOhms).
3. At least 3 set-points must be used but no more than 10 set-points can be
used. If any one of the set-points is more than 5 degrees below 0C (9 de-
grees below 32F or 5 degrees below 273.15 K), at least 4 set-points must
be used.
Note: This software automatically determines if the BETA coefficients
need to be calculated based on the following criteria:
• The reference reading closest to 0C is not used to determine whether
BETA is calculated.
• If any other reference reading is below 0C, BETA will be calculated.
• Otherwise, BETA will not be calculated.
4. One of the set-points used should be close to 0C. This is not a require-
ment, however, results of the calculations become less reliable when no
reading is near 0C because the software must extrapolate this reading.
5. The residuals are calculated for each set-point used in calculating the co-
efficients. Residuals are always in the same scale as the reference probe
readings.
15.12.4 Polynomial Requirements
The following requirements must be met when Polynomial is selected as the
type of coefficients to calculate for platinum or thermistor probes. For more in-
formation concerning the method used to calculate the Polynomial coefficients,
refer to Section 15.12.6, Methods Used for Calculating Coefficients.
1. The reference probe readings must be in temperature (C, F or K).
Note: The accepted thermistor model is based upon the logarithmic resis-
tance-temperature characteristic in terms of absolute temperature (K). The
accuracy of a model based upon degrees F or degrees C has net been
tested. Therefore, polynomial coefficients for thermistor probes are always
calculated using K. If reference readings are entered in degrees F or de-
grees C, the readings are converted to their K equivalent values before the
fit is computed.
2. The UUT (test probe) readings must be in resistance (Ohms or kOhms).

3. The order of the polynomial must be selected. Allowable choices are
from 3rd order to 9th order for platinum probes and from 3rd order to
6th order for thermistor probes.
4. For thermistor probes, the Steinhart-Hart method may be selected. Stud-
ies have indicated no significant loss in accuracy when using the
Steinhart-Hart method (eliminating the squared term) over the range of
–2C to 70C (28F to 158F). The formula used when the Steinhart-Hart
method is selected is:

For more information on this topic, refer to “Worldwide Capability in
Thermistors”, Thermometrics, Inc., 1993, pages 14-15.
5. For normal calculations, at least 4 set-points must be used but no more
than 10 set-points can be used.
6. For Steinhart-Hart calculations, only 3 set-points should be used.
7. The minimum number of set-points used must exceed the order of the
polynomial by at least 1 (i.e. for a 5th order polynomial, at least 6
set-points must be used).
8. The residuals are calculated for each set-point used in calculating the co-
efficients. Residuals are always in the same scale as the reference probe
readings. For platinum probes, the residuals are in degrees. For thermis-
tor probes, residuals are in millidegree.
15.12.5 Thermocouple Requirements
The following requirements must be met when calculating coefficients for
Thermocouple probes. For more information concerning the method used to
calculate the Thermocouple coefficients, refer to Section 15.12.6, Methods
Used for Calculating Coefficients.
1. The reference probe readings must be in temperature (C, F or K).
Note: The algorithm used to calculate thermocouple coefficients forces the
EMF at 0C to 0.0µV. Therefore, using a set-point at or near 0C when calcu-
lating thermocouple coefficients may cause erroneous results. For best re-
sults, use at least two set-points that are not near 0C (more than ±5C).
2. The UUT (test probe) readings must be in voltage (mV or µV). At least 2
set-points must be used but no more than 10 set-points can be used.
3. The CJC readings, if used, can be in either temperature (C or F) or volt-
age (mV or µV). If no CJC readings are needed, a scale does not need to
be selected.
4. The thermocouple type must be selected. The following types can be
selected:

*Selecting this range allows the software to automatically select the appropriate reference function to use to calculate the EMF at each tem-
perature. Selecting one of the other ranges forces the reference function for the selected range to calculate the EMF for ALL temperatures
to be used.
6. Each set-point for thermocouple probes can have an associated Cold
Junction Compensation (CJC) reading. The UUT reading at each
set-point is adjusted according to the CJC value for that set-point prior to
calculating coefficients. The UUT readings are not adjusted prior to cal-
culating coefficients if the Do not use CJC in calculations option is
selected.
7. The residuals are calculated for each set-point used in calculating the co-
efficients. For thermocouple probes, the residuals are in the same scale as
the UUT readings (mV or µV).

15.12.6 Methods Used for Calculating Coefficients
The following sections describe the methods used to calculate coefficients.
15.12.6.1 General
The thermometric expressions used by this software are well known expres-
sions and as such are described in detail elsewhere. This section touches on
some specifics as they relate to the methods used to arrive at solutions.
The coefficients for all solutions with the exception of the IPTS-68 platinum
probe are calculated using matrix methods. The IPTS-68 platinum probe solu-
tion is calculated using iteration. The solutions are either exact solutions or
over-determined solutions depending on the number of test points used in rela-
tion to the number of test points required. Exact solutions result when the exact
number of test points required for simultaneous solution of sets of equations
are used (i.e., two coefficients from two test points). Over-determined solutions
result when more test points are used than the unknowns require (i.e., two coef-
ficients from three or more test points).
15.12.6.2 ITS-90
The ITS-90 is expressed in terms of resistance ratio (W) vs. temperature (K)
rather than resistance (R) vs. temperature. The resistance ratio is defined as the
resistance at a temperature R(t) divided by the resistance at the Triple-Point of
Water R(TPW), or:
W = R(t)/R(TPW)
Because ratios are used in the ITS-90, the RTPW is required in addition to the
resistance values at the test temperatures, thus, three test points are required to
solve for two coefficients. The example below shows a set of four equations
representing data at five temperatures (RTPW and resistance at four test tem-
peratures) along with the matrix method used to solve the over-determined set.

15.12.6.3 IPTS-68
Like the ITS-90, the IPTS-68 is expressed in terms of resistance ratios. The de-
nominator, however, is the resistance at the ice point (0.0C) rather than the re-
sistance at the Triple-Point of Water (0.01C). This software allows only exact
solutions for the IPTS-68 and uses iteration or simple algebra for the solutions.
15.12.6.4 Callendar-Van Dusen
The Callendar-Van Dusen expression is basically a third order polynomial with
the third coefficient (β) set to zero above 0C. The polynomial is expressed in
terms of resistance vs. temperature in degrees C. It is solved by matrix methods
in a similar manner as the ITS-90 expression shown above with temperature on
the left of the equal sign and the polynomial on the right. The software allows
for over-determined solutions. Only data above 0C is used for solution of the
first two coefficients (α and δ), data both above and below 0C is used for solu-
tion of β.
15.12.6.5 Polynomial and Thermocouple
Polynomial solutions are arrived at using matrix methods as with the ITS-90
and the Callendar-Van Dusen. Platinum probes require polynomials expressed
in terms of resistance vs. temperature. Thermistor probes exhibit exponential
resistance vs. temperature relationships and the polynomials used are exponen-
tial expressions in terms of resistance vs. temperature. The polynomials can be
of any order up to 9th for platinum probes and up to 6th for thermistor probes.
The software allows for over-determined solutions. Thermocouple probes re-
quire polynomials expressed in terms of mV vs. temperature.
15.12.7 Table Temperature Range Chart
Due to the nature of the equations used to generate tables, the temperature
range that can or should be used to generate a table depends on the type of co-
efficients used. Table 3 provides details on the temperature range for specific
coefficients.

17.1 Limitations
There are a few known limitations to using the report viewer utility. Please read
the following information to avoid potential problems:
• Report files are dependent on the currently selected Windows® printer
driver. For this reason, select the driver for the printer that is used to print
the report prior to saving the report to a file. For example, if the report file
is being e-mailed to a person who prints the report on a Hewlett-Packard
LaserJet 4MP printer, select this same print driver prior to previewing and
saving the report to a file. Otherwise, reports may appear fine in the pre-
view window but print incorrectly.
• Report files use a proprietary format and are not viewable by any other
software such as Adobe® Acrobat Reader, word processors, or graphics
applications. The report viewer utility can be distributed freely to anyone
who needs to view or print a report file. To create a distribution diskette
for the report viewer utility, refer to Section 17.3, Making a Report
Viewer Utility Setup Diskette.
• Report files which contain a table (from Coefficients and Tables applica-
tion) may contain one or more blank pages before the actual table data
starts. This is done to preserve the correct page numbering as selected
when the table was generated. To avoid blank pages, start the page num-
bering for the table at page 1. Otherwise, simply discard the blank pages
after printing the table.
17.2 Report Files

18.2 Communication Error
If MET/TEMP II is unable to communicate with an instrument for any reason,
a communication error occurs.
To resolve the communication error, please check the following:
• Is the COM port in use? – Make sure that the COM port is not currently
being used by another application. If there is a hot sync adapter for a PDA
connected to your computer, make sure the software that uses the adapter
is closed or that it is not trying to use the same COM port.
• Is the correct COM port selected? – Make sure that the communication
cable is connected to the selected COM port on the computer.
• Is the instrument set to the right baud rate? – Make sure that the in-
strument’s baud rate is set to 2400 baud. Refer to the instrument’s User’s
Guide for more details on how to set the baud rate.
• Is the right type of cable being used? – MET/TEMP II requires that a
“null modem” cable be used to connect instruments to the SmartSwitch
box and a “straight through” (parallel) cable to connect the SmartSwitch
to the computer’s COM port.
• Is the instrument turned on? – Make sure that the instrument is turned
on. Use the buttons on the front panel of the instrument to exit from any
open menu.
• Is the correct model selected? – Make sure that the selected instrument
model matches the model of the instrument being used.
18.3 Troubleshooting Common Problems
The following table outlines some possible problems that may arise when using
MET/TEMP II and some possible solutions to those problems:
