Operation
NOTE:
1. Adobe Reader software is required.
2. Program the logger and generate the PDF
report at room temperature. For example: if
the logger is removed from a freezer, it should
be allowed to return to the ambient room
temperature before generating the PDF
report.
3. The executable file for programming the
logger is named: PDF Logger Configuration
Tool
Step1 Configuring the data logger
It is possible to make configuration changes at
anytime before the logging function is started.
Once the logger is started, configuration changes
cannot be made anymore. If the logger is locked
with a Password, the Password is required to
make configuration changes.
- First, connect the data logger to a PC via the
USB port. The green LED is on while the
connection with computer is built.
- Windows file management window will appear.
- If the correct file folder is not open, click on
Folder to view files.
- Open the file " PDF Logger Configuration Tool.
exe".
- The default language is English. The user may
change it to one of six alternate languages. There
are English, German, French, Italian, Spanish,
and Portuguese.
- User programmable parameters are as follows:
★Sampling rate
Select the sampling interval you need from 30
seconds to 2 hours.
★Start delay
Select the start delay from 0 min to 24 hours. For
example: If the delay is 5 minutes, and the
sampling rate is 10 minutes, the real time to log
the first temperature measurement is 5 minutes
after the GO key is pressed. All measurements
after the first measurement will be at a 10 minute
(or selected) interval.
★Unit of Measurement (UoM)
Select the unit that will be displayed on the report.
The selections are Celsius or Fahrenheit
★Password
The Password function is default OFF. The user
may enable it to prevent unauthorized
reprogramming prior to pressing the logger
starting key. A Password may have up to 16
alpha or numeric characters.
★Company Name
A user defined name, location or descriptor, can
be input under Company Name. It will be
displayed on the PDF report as the Title, with a
maximum of 20 characters.
★Alarm types
Regardless of the Alarm Type, if the red LED is
triggered, it won’t stop even the reading return to
normal range or logging is stopped. The way to
stop red alarm LED is to plug logger into
computer to generate report.
Single: an alarm is triggered immediately when
the measured value exceeds the alarm threshold.
Cumulative: an alarm is not triggered when the
measured value exceeds the alarm threshold, but
only once the overall average value during alarm
delay duration exceeds the alarm threshold.
Disable: No alarm function during the logging
process
★Alarm delay
The preset alarm delay interval for a single alarm
type is always ZERO.
The adjustable alarm delay interval for a
cumulative alarm type can be 5 minutes to 2
hours.
★Alarm Limits
Select the alarm threshold values. For example: if
2 - 8 deg C is selected, it means that an alarm
condition will occur below 2 deg C, or above 8
deg C. The programmable alarm limit of each
parameter is limited to one decimal. To
summarize, to activate a alarm when 30 min
average value of hazardous alarm delay period is
higher than 8
℃
, please program the alarm delay
as 30 mins, alarm type as cumulative and range
as 2~8
℃
★Time zone
Before programming the logger the user must
assure that the PC is set for the correct time zone.
The logger will auto synchronize to the time zone
of the PC, when Save is pressed. Time zone
changes over the transit distance are not
adjusted in the logged data.
The default value of above parameters are:
Sampling rate: 5 min Alarm Type: Disable
Start delay: 0 min Alarm delay: 0 min
Temp. Unit: °C Alarm Limits: blank
Password: disable
Company Name: blank Language: English
Once all the programming is done, press "Save"
to confirm the setting and then you may close the
setup window and remove the logger from PC
USB port.
Step2 Start logging
-When logger is successfully programmed, the
green LED blinks triple every 5 seconds to
indicate the logger is in standby mode.
-Put on the USB plug cover and then press "GO"
key for five seconds to start the logging.
-Red LEDs will flash in sequence 3 times to
indicate the logging is activated.
-During the logging, the green LED will blink
every ten seconds. If battery power is too low to
maintain a normal operation, red LED blinks.
- To place a bookmark manually during the
delivery transition, press MARK key for 5
seconds till the Red LEDs flash in sequence.
Step3 Download data
-Press "GO" key for 5 seconds till red LEDs flash
in sequence to stop the logging.
-Plug logger into PC USB port can also stop the
logging
- The PDF report will be generated automatically
upon the logging is plugged into computer. The
report contains statistics report, diagram and all
detail data. The language of the report is identical
to the language you used to do setting.
-The generated PDF report will be kept in logger.
You may copy and paste it to any file folder you
need.
-The recording function of this logger is ended
while you plug it into computer or press key to
stop it.
