LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service. The warranty period is two years and begins on
the date of shipment. Parts, product repairs, and services are warranted for 90 days. This warranty extends only to the original buyer or end-user customer of a
Fluke authorized reseller, and does not apply to fuses, disposable batteries, or to any product which, in Fluke's opinion, has been misused, altered, neglected,
contaminated, or damaged by accident or abnormal conditions of operation or handling. Fluke warrants that software will operate substantially in accordance with its
functional specifications for 90 days and that it has been properly recorded on non-defective media. Fluke does not warrant that software will be error free or operate
without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to extend a greater or different
warranty on behalf of Fluke. Warranty support is available only if product is purchased through a Fluke authorized sales outlet or Buyer has paid the applicable
international price. Fluke reserves the right to invoice Buyer for importation costs of repair/replacement parts when product purchased in one country is submitted for
repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or replacement of a defective product which is returned
to a Fluke authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center to obtain return authorization information, then send the product to that service
center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). Fluke assumes no risk for damage in transit. Following warranty repair,
the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that failure was caused by neglect, misuse, contamination,
alteration, accident, or abnormal condition of operation or handling, including overvoltage failures caused by use outside the product’s specified rating, or normal
wear and tear of mechanical components, Fluke will provide an estimate of repair costs and obtain authorization before commencing the work. Following repair, the
product will be returned to the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).
THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE FOR
ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR
THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or consequential damages, the
limitations and exclusions of this warranty may not apply to every buyer. If any provision of this Warranty is held invalid or unenforceable by a court or other decision-
maker of competent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

Thin-Flexi Current Probe
The Thin-Flexi Current Probe works on the Rogowski coil (R-coil)
principle that is a toroid of wire used to measure an alternating current
through a wire encircled by the toroid. See Figure 3.
Figure 3. R-Coil Operation Principle
The R-coil has advantages over other types of current transformers:
•
It is not a closed loop. The second terminal is passed back through
the center of the toroid core (commonly a plastic or rubber tube)
and connected along the first terminal. This allows the coil to be
open-ended, flexible, and able to be wrapped around a live
conductor without disturbing it.
•
It has an air core rather than an iron core. It has a low inductance
and can respond to fast-changing currents.
•
Because it has no iron core to saturate, it is highly linear even
when subjected to large currents, such as those used in electric
power transmission or pulsed-power applications.
A correctly formed R-coil, with equally spaced windings, is largely
immune to electromagnetic interference.

Use the color clips for easy identification of the four current probes.
Apply the clips that are appropriate for your local wiring codes on both
ends of the current probe cable. See Figure 4.
Figure 4. Test Leads with Color Coding
Kensington Lock
A Kensington Security Slot (also called a K-Slot or Kensington lock) is
part of a built-in anti-theft system. It is a small, metal-reinforced, oval
hole found on the right side of the Logger (see item 6 in Table 4). It is
used for attaching a lock-and-cable apparatus. The lock is secured in
place with a key or combination lock attached to a plastic-cover metal
cable. The end of the cable has a small loop that allows the cable to
be looped around a permanent object, such as a cabinet door, to
secure it in place. This lock is available from most electronics and
computer suppliers.

Storage
When not in use, keep the Logger in the protective storage bag/case.
The bag/case has sufficient space for the Logger and all the
accessories.
If the Logger is stored for an extended period of time or is not in use
for a long time, you should charge the battery at least once every six
months.
Tilt Stand
The power supply includes a tilt stand. When used, the tilt stand
positions the display at a good angle for use on a tabletop surface. To
use, attach the power supply to the Logger and open the tilt stand.
Power Supply
The Logger includes a removable power supply, see Figure 5. The
power supply is either attached to the Logger or used externally with a
dc power cable. The configuration with the externally connected
power supply is preferred in locations where the Logger with the
power supply attached is too big to fit in a cabinet.
When the power supply is connected with the Logger and connected
to line power, it:
•
converts line power to dc power and is used directly by the Logger
•
automatically turns on the Logger and continuously powers the
Logger from the external source (after initial power on, the power
button turns on and turns off the Logger)
•
recharges the battery
The power cord/measurement line cover slides to select the input
source.
Warning
To prevent possible electrical shock, fire, or personal
injury, do not use the power supply if the mains power
cable/measurement line slide-cover is missing.

Note
Be aware that for power measurements in 3-phase systems:
• Total Active Power (W) is the sum of the individual
phases.
• Total Apparent Power (VA) also includes the neutral
current that can result in a very different result than the
sum of the three phases. This is especially noticeable
when a signal is connected to all three phases (for
example, a calibrator) the total value is approximately
41 % higher than the sum of each phase.
• Total Fundamental Power (W and var) only delivers the
sum of each phase when the phase rotation is
clockwise. It is zero when the phase rotation is counter-
clockwise.

Harmonics Spectrum Relative to Harmonic Limits
This feature is available on 1738 or 1736 with 1736/Upgrade on
installation of the IEEE 519/Report license. The screen shows the
harmonics relative to the individual limit defined by a user-selected
standard. The standard is selected in the Measurement Configuration.
Each bar is green when the measurement is below the individual limit
for this harmonic or THD, otherwise, the bar turns red. The number of
displayed harmonics varies in accordance with the selected standard.
Note
This screen provides quick feedback about the harmonic
levels compared to Power Quality standards. It is no proof of
compliance to the standard. The average calculation interval
of 1 second is much more frequent compared to the
10 minutes required by applicable standards. A limit violation
in this screen does not necessarily result in a standards
violation. For example, when the measurement values
surpass the maximum allowed tolerance during a short time
period. Use the feature to record data in logging sessions and

Study Type
Depending on the application, select either Load Study or Energy
Study.
•
Energy Study: Select this study type when voltage
measurements for a power quality assessment and power and
energy values that include active power (W) and PF are required.
•
Load Study: For convenience, some applications require you to
measure only the current that makes the connection to the point to
measure.
Typical applications are:
•
Verify the circuit capacity before adding additional load.
•
Identify situations where the allowable load can be exceeded.
Optionally, a nominal voltage can be configured to get pseudo-
apparent power readings.
Power Quality
Select the power quality standard (available on 1738 or 1736 with
1736/Upgrade or IEEE 519/Report license) for compliance evaluation.
EN 50160: voltage characteristics of electricity supplied by
public distribution networks.
The Logger supports these parameters:
•
Frequency
•
Voltage Variations
•
Voltage Harmonics and Voltage THD
•
Unbalance
•
Events
IEEE 519: recommended practice and requirements for harmonic
control in electric power systems.
The standard defines limits for voltage harmonics, voltage THD,
current harmonics, and TDD (total demand distortion). The limits for
current harmonics and TDD depend on the ratio of maximum demand
load current I
L
to the short circuit current I
SC
. Set the values with
and .
Note
If the values of I
SC
and I
L
are not currently available, you can
update these values at a later time with the Energy Analyze
Plus software.
Set the Harmonics Standard to off when the harmonics compliance
evaluation is not required.

Nominal Voltage
Select a nominal voltage from the list. If a voltage is not shown in the
list, enter a custom voltage. On energy studies, the nominal voltage is
required to determine the limits for dips, swells, and interruptions.
The nominal voltage on load studies is used to calculate the pseudo
apparent power:
nominal voltage x measured current
Set the nominal voltage to off if the apparent power readings are not
required.
Voltage Ratio (only in energy studies)
Configure a ratio factor for the voltage inputs when a potential
transformer (PT) is in series with the voltage connections such as
when you want to monitor a medium-voltage network. The default
value is 1:1.
Nominal Frequency
Set the nominal frequency to be the same as the power line
frequency, 50 Hz or 60 Hz.
Current Range
Configure the current range of the attached sensor. Three ranges are
available:
•
Auto
•
Low Range
•
High Range
When set to Auto, the current range is set automatically and depends
on the measured current.
Low Range is 1/10 of the nominal range of the attached current
sensor. For example, the low range of an iFlex1500-12 is 150 A.
High Range is the nominal range of the attached current sensor. For
example, 1500 A is the nominal range on an iFlex1500-12.
Note
Set the current range to Auto when you are not sure about
the maximum current during the logging session. A specific
application can require you to set the current range to a fixed
range rather than Auto. This can occur because the Auto
range is not gapless and may lose too much information in
the case of a highly fluctuating current.
Current Ratio
Configure a ratio factor for the current sensors when a current
transducer (CT) is used to measure the much higher level on the
primary side at a substation or step-down transformer that has a built-
in metering current transformer.
The current ratio can be used to increase the sensitivity of the iFlex
sensor. Wrap the iFlex sensor around the primary conductor, for
example 2X, and enter a ratio factor of 1:2 to get correct readings. The
default value is 1:1.

standard EN 50160.
The screen includes the parameters for:
•
Frequency
•
Voltage Variations
•
Voltage Harmonics
•
Unbalance
•
Events
The frequency, unbalance, and events have a single bar. Voltage
variations and voltage harmonics are shown in three bars that depend
on the configured topology.
The length of a bar increases if the related parameter is further away
from its nominal value. The bar turns from green to red if a maximum
allowed tolerance requirement is surpassed. When the standard
defines two limits for a parameter (for example, voltage variations
have a limit for 95 % of the time and limit for 100 % of the time) the bar
changes from green to orange when the parameter surpasses the 95
% limit but does not exceed the 100 % limit. For more information go

The unbalance value u2 (negative sequence ratio) is the ratio of
negative sequence divided by positive sequence and is shown as a
percentage.
In the case of a counter-clockwise rotating system, the unbalance
would show values exceeding 100 %. In this case the ratio positive
sequence divided by negative system is calculated which results in
values lower or equal to 100 %.
Note
The unbalance is only available in three phase delta and Wye
systems, excluding the balanced systems.
Harmonics
Use
(Harmonics) to access the harmonics analysis screens for
voltage and current.
Harmonics Spectrum
The harmonics spectrum is a bar chart of the harmonics h02 ... h50.
When % of the fundamental is selected, THD is included in the chart.
The bar chart in absolute units (V RMS, A RMS) includes the
fundamental. Use the trend chart to show the exact value.
Trend Chart
The trend chart is a chart of the fundamental, a selectable harmonic,
or THD. A split screen shows the harmonics spectrum in the upper
graph and the trend chart in the lower graph. Touch the bar chart or

Harmonics Spectrum Relative to Harmonic Limits
This screen is available on 1738 or 1736 with 1736/Upgrade or
IEEE519/Report license) and shows the harmonics relative to the
individual limit defined by the standard selected in the measurement
configuration. Each bar is green when the measurement is below the
individual limit for this harmonic or THD. When the standard defines
two limits, for example, a limit for 95 % of all values and a limit for 99 %
of all limits, the bar turns orange when the measurement values
comply with the 99 % limit but violate the 95 % limit. When both limits
are exceeded the bar turns red. When the standard defines only one
limit for each harmonic or THD, the bar turns from green to red when
this limit is exceeded. The number of displayed harmonics varies in
accordance with the selected standard.
The side menu in the harmonics screens has a dual use. First, select
the parameter to display and confirm with
. The selector bar jumps
to the lower section for the phase selection. The number of available
phases and the Neutral current depends on the selected topology.
See Measurement Configuration on page 23 for details. Make your
choice and confirm again with

menu. Use

Events
The Logger captures events on voltage and current. The events are
shown in a table with the columns ID, Start Time, End Time, Duration,
Event Type, Extreme Value, Severity, and Phase. Touch the arrows
left and right of the table to view all available columns. Use / to
highlight an event of interest. On the 1738 or the 1736 with
1736/Upgrade license, use
(Waveshape) and (RMS
Profile) to review the recordings triggered with the start of the event.
The voltage events are classified in dips, swells, and interruptions and
are measured according to the standard IEC 61000–4–30
"Electromagnetic compatibility (EMC) - Part 4-30: Testing and
measurement techniques - Power quality measurement methods".
According to this standard the Logger applies the polyphase event
detection on split phase and three phase systems with the exception
of the topologies 3-phase Delta balanced and the 3-phase Wye
balanced. The events are captured and reported for phase A/L1 only.
Note
The polyphase event detection simplifies the event table
because events on multiple phases are combined when they
occur at the same time or overlap. In the Energy Analyze
Plus software you can select to get either a table with
combined events using the polyphase event detection or a
table with events for each individual phase in order to review
details, like start time, end time, or the extreme value on an
individual phase of interest.

Supply Voltage Swells
On single-phase systems, a swell begins when the voltage rises
above the swell threshold, and ends when the voltage is equal to or
below the swell threshold minus the hysteresis voltage. See Figure 7.
On polyphase systems, a swell begins when the voltage of one or
more channels is above the swell threshold and ends when the
voltage on all measured channels is equal to or below the swell
threshold minus the hysteresis voltage.
Figure 7. Characteristics of a Voltage Swell
On single-phase systems, a voltage dip begins when the voltage falls
below the dip threshold, and ends when the voltage is equal to or
above the dip threshold plus the hysteresis voltage. See Figure 8.
Figure 8. Characteristics of a Voltage Dip
On polyphase systems, a dip begins when the voltage of one or more
channels is below the dip threshold and ends when the voltage on all
measured channels is equal to or above the dip threshold plus the
hysteresis voltage.

Supply Voltage Interruptions
On single-phase systems, a voltage interruption begins when the
voltage falls below the voltage interruption threshold and ends when
the value is equal to or greater than the voltage interruption threshold
plus the hysteresis. See Figure 9.
Figure 9. Characteristics of a Voltage Interruption
On polyphase systems, a voltage interruption begins when the
voltages of all channels fall below the voltage interruption threshold
and ends when the voltage on any one channel is equal to, or greater
than, the voltage interruption threshold plus the hysteresis.
Note
On polyphase systems, the event is still classified as a dip
when the voltage of only one or two phases falls below the
interruption limit.
Inrush Current
Inrush currents are surge currents that occur when a large, or low-
impedance load comes on line. Normally the current will stabilize after
some time when the load has reached normal working condition. For
example the start-up current in induction motors can be 10x the
normal working current. See Figure 10.
The inrush current begins when the 1/2-cycle RMS current rises
above the inrush threshold, and ends when the 1/2-cycle RMS current
is equal to or below the inrush threshold minus the hysteresis value. In
the event table the extreme value is the highest 1/2-cycle RMS value
of the event.

client, the passphrase is also called Security Key, Password, or
similar.
After a few seconds the connection is established.
Note
On Windows, the WiFi icon in the notification area of the
task bar is shown with an exclamation mark. The exclamation
mark indicates that this WiFi interface does not provide an
Internet access. This is normal since the Logger is not a
gateway to the Internet.
WiFi-Infrastructure
The WiFi connection requires the WiFi-Infrastructure license and
supports WPA2-PSK. This connection requires a DHCP service
running in the access point to assign IP addresses automatically.
To establish a connection with a WiFi-access point:
1.
In WiFi Configuration screen, push / to highlight Name
(SSID) and push
.
A list of access points within range shows. Icons show the
field strength. Avoid access points with no or only one green
bar since they are too far away for a reliable connection.
2.
Push / to highlight an access point and push to
confirm.
3.
In WiFi Configuration screen, push / to highlight
Passphrase and push
.
4.
Enter the passphrase (also called Security Key or Password) and
push . The passphrase has 8 to 63 characters and is
configured in the access point.
The assigned IP address shows when the connection is
successful.
