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 decision­maker of competent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

Voltage Test Leads

Voltage test leads are four-core, flat, test leads that do not tangle and
can be installed in tight spaces. On installations where the access to
Neutral is out of reach with the three-phase test lead, use the black
test lead to extend the Neutral lead.

For single phase measurements use the red and black test leads.

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 cable markers for easy identification of the four current
probes. Apply the markers on both ends of the current probe cable.
See Figure 4.

Figure 4. Test Leads with Cable Markers

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 3). 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.

Power Logger

Storage

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.

XW 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.

The battery charge is faster when the Logger is turned off.

To charge the battery:

1.

Connect the mains cord to the ac input socket on the power
supply.

2.

Fit the power supply to the Logger or use the dc power cord to
connect the power supply to the Logger.

3.

Connect to mains power.

Note

• Li-ion batteries keep a charge longer if stored at room
temperature.

• The clock resets when the battery is completely
discharged.

• When the Logger shuts off because of a low battery,
enough battery capacity is available to back up the real­time clock for up to 2 months.

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 counter­clockwise.
