Warning
A Warning identifies conditions and actions that pose ha-
zards to the user. To avoid electrical shock or personal injury,
follow these guidelines:
• Do not point laser directly at eye or indirectly off
reflective surfaces.
• Before using the thermometer inspect the case. Do not
use the thermometer if it appears damaged. Look
for cracks or missing plastic.
• Replace the batteries as soon as the battery indicator
two or less segments.
• Do not use the thermometer if it operates abnormally.
Protection may be impaired. When in doubt, have the
thermometer serviced.
• Do not operate the thermometer around explosive gas,
vapor, or dust.
• Do not connect the optional external probe to live
electrical circuits.
• To avoid a burn hazard, remember that highly reflective
objects will result in lower than actual temperature
measurements.
• Do not use in a manner not specified by this manual or the
protection supplied by the equipment may be impaired.
Caution
To avoid damaging the thermometer or the equipment under
test protect them from the following:
• EMF (electro-magnetic fields) from arc welders,
induction heaters, etc.
• Static electricity
• Thermal shock (caused by large or abrupt
ambient temperature changes- allow 30 minutes
for thermometer to stabilize before use).
• Do not leave the thermometer on or near
objects of high temperature.

The Fluke Model 572 Infrared Thermometer (the
thermometer) is for non-contact temperature
measurement. This thermometer determines
an object‘s surface temperature by measuring
the amount of infrared energy radiated by the
object‘s surface.

Batteries and Measurement
To open the battery
compartment, press
gently on the top part of
the handle
to release
the catch and pivot the
grip as shown in the
figure. Orient the batteries
(two alkaline R6 (AA,
UM3)) positive side up as
shown on the housing.
To take a temperature
measurement, hold the
unit as shown. Aim at the
target. Pull the trigger (F).
The temperature of the
object being measured
is shown on the display
(B).
The temperature will
be displayed for seven
seconds after trigger is
released.

Make sure that the target is larger than the unit’s
spot size. The smaller the target, the closer you
should be to it.

The measured spot size depends on the dis-
tance between the object you are measuring and
the infrared thermometer.
The relationship between distance and spot size
is 60:1(Standard Focus) or 50:1 (Close Focus) at
the focus point. The D:S in the far field (>33ft/
10m) is 35:1 (Standard) or 12:1 (Close Focus).

EMISSIVITY

C
The amount of infrared
energy radiated by an
object depends on its
emissivity and its
temperature.
The emissivity depends
on the material and its
surface characteristics.
For more accurate
readings, adjust the
emissivity value for the
type of material being
measured
.
The “Setup” DIP switch
(located inside the unit’
s
handle) must be in the
“ON” position to adjust the
emissivity.
When the trigger is pulled,
the display will show an
emissivity value (4). To
set it to another value,
use the up and down keys
(C).

Maintenance
Lens Cleaning:
Blow off loose particles
using clean compressed
air. Brush remaining de-
bris away with a camel’s
hair brush.
Wipe the surface with a
moist cotton swab. The
swab may be moistened
with water or a water
based glass cleaner.
NOTE: DO NOT
use sol-
vents to clean the
plastic lens.
Cleaning the Housing:
To clean the exterior
housing, use soap and
water or a mild commer-
cial cleaner. Wipe with a
damp sponge or soft rag.
