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

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.

Primary and Secondary Triggers
The two-part trigger is located in the standard trigger position for a pistol-grip device. The
larger, green trigger is the primary trigger. The smaller, black trigger is the secondary trigger.
Use the primary trigger to capture an image to save or edit. Use the secondary trigger to open
the Asset Identification mode to scan a QR code or barcode to attach an asset to an image.
Basic Operation
Turn On and Off the Product
Before you use the Product for the first time, charge the battery. See Charge Batteries.
To turn on the Product, push and hold O for 1 second. To turn off the Product, push and hold
O for 2 seconds.
With the Product on, push and release O to NUC (calibrate) the camera sensor.
Note
All thermal Imagers need sufficient warm-up time for accurate temperature
measurements and best image quality. Warm-up time can vary by model and
environmental conditions. Although most Imagers are fully warmed up in 3 minutes to
5 minutes, wait a minimum of 10 minutes if the most accurate temperature
measurement is important to your application. When you move an Imager between
environments with large differences in ambient temperature, allow for additional
adjustment time.
Capture Image
To capture an image:
1. Focus on a target.
2. Push and release the Primary Trigger button or double tap on the display to capture and
freeze the image.
The image is in the memory buffer for you to save, add or remove an asset ID, or edit.
Note
Asset ID tags, flags, and notes can be saved with images captured in .is2 file format
only. To select .is2 file format, see Device Settings Menu.

To use the temperature range high and low values on the display for future measurements:
1. Set Level/Span to Manual.
2. Push a to rescale the display and save the temperature values on the display at that
time.
To use a different temperature range, use the arrow keys to change the Level/Span, or
push a twice to rescale.
Note
The Imager always powers up in the same Level/Span mode, Auto or Manual, as when
the Imager was powered down.
Emissivity Adjustment
All objects radiate infrared energy. The actual surface temperature and emissivity of the target
affects the quantity of energy radiated. The Imager senses the infrared energy from the
surface of the target and uses the data to calculate an estimated temperature value. Many
common materials such as wood, water, skin, cloth, and painted surfaces, including metal,
radiate energy well and have a high emissivity factor of ≥90 % (or 0.90). The Imager measures
temperatures accurately on targets with a high emissivity.
Shiny surfaces or unpainted metals do not radiate energy well and have a low emissivity factor
of <0.60. For the Imager to calculate a more accurate estimate of the actual temperature of
targets with a low emissivity, adjust the emissivity setting.
Warning
To prevent personal injury, see emissivity information for actual temperatures.
Reflective objects result in lower than actual temperature measurements. These
objects pose a burn hazard.
Set emissivity as a direct value or from a list of emissivity values for some common materials.
If the emissivity value is <0.60, a caution shows on the display.
Note
Surfaces with an emissivity of
<
0.60 make it difficult to determine reliable and
consistent actual temperatures. The lower the emissivity is the greater the potential of
error is when the Imager calculates the temperature measurement because more of
the energy reaching the camera is specified as background temperature. This is also
true even when adjustments to the emissivity and reflected background adjustments
are performed properly.

Transmissivity
When you do infrared inspections through IR windows, not all of the infrared energy emitted
from the target is transmitted through the optical material in the window. If you know the
transmission percentage of the window, adjust the transmission percentage in the Imager or in
Fluke Connect desktop software to improve the accuracy of the measurement.
When you do not do infrared inspections through an IR window, set Transmissivity to 100 % to
disable the correction percentage.
Image Menu
The IR-Fusion slider bar sets the Product to take images from full visible light mode to full
IR-Fusion mode. Use a blend between visible light mode and IR-Fusion to view an object with

To adjust the IR-Fusion level:
1. Tap A.
2. Use the slider bar to set the IR-Fusion level.
Alternatively, you can adjust the IR-Fusion level in camera mode:
With Level/Span set to Auto, push Y or Z to change the IR-Fusion level.
Or,
