HOW IT WORKS
Infrared thermometers measure the surface
temperature of an object. The unit’s optics sense
emitted (E), reflected (R), and transmitted (T)
energy, which is collected and focused onto a
detector. The unit’s electronics translate the
information into a temperature reading which is
displayed on the unit.
HOW TO OPERATE THE UNIT
C/F and Battery
Pull open the unit’s handle using the finger indents
near the trigger to access the C/F switch or to insert/
remove the battery. To toggle between °C and °F,
push the switch (A). Insert the 9v battery positive
side first into the battery compartment.
Note: The battery door is detachable.
Operating the Unit
To measure a temperature, point unit at object and
pull the trigger. Be sure to consider distance-to-spot
size ratio and field of view. If the unit is equipped
with a laser, use the laser only for aiming. See How
to Accurately Measure Temperatures.
Display
The backlit LCD displays the current temperature in
Celsius or Fahrenheit. The unit will hold the reading
for 7 seconds after trigger is released; the word
HOLD appears. The presence of the battery icon
indicates a low battery (B).
HOW TO ACCURATELY MEASURE TEMPERATURE
Locating a Hot Spot
To find a hot spot aim the thermometer outside the
area of interest, then scan across with an up and
down motion until you locate the hot spot.
