● Avoid operating near strong electromagnetic
fields such as arc welders, induction furnaces,
etc.
● Do not expose thermometer to excessive
ambient temperatures.
● Keep the thermometer clean and avoid getting
dust into the detector’s optics.
● Do not use solvents to clean the meter.

5. Measurement Principle
Infrared thermometers detect infrared energy
emitted by objects. The instrument focuses
energy through its lens, changing the
temperature of a special material that creates an
electrical signal. A microcomputer processes this
signal and displays the output on the panel of the
thermometer. The laser is used only for sighting
the instrument and has no other effect on
temperature measurement.
6. Measurement Method
1. To measure the temperature of an object, aim
the unit at the object and press the trigger. As
long as you hold the trigger, you can measure
temperature continuously. After releasing the
trigger, the LCD will hold the temperature values.
The first display indicates the current value.
The second display indicates the calculated (Avg.,
MAX, MIN or MAX-MIN).

2. Use the laser button to activate the laser for
aiming at distant objects.
3. Use the backlight button to illuminate the
display in low-light conditions.
4. Press the “MODE” button to change the
second temperature display. This display can
show AVG (average), MAX (maximum), MIN
(minimum), MAX-MIN (span) or Alarm (Only
model B).
5. Press the °C/°F button to change the unit of
measure.
6. (Only model B) Press “+” button to add the
emissivity, and press “-” to reduce the emissivity.
(Please refer to the chapter 8 “Emissivity”.)
7. (Only model C) Press “MODE” button, when
“ALARM” symbol appears, you can set the
alarming temperature value. Press “+” to add the
alarming temperature value, and press “-” to
reduce it. (Please refer to the chapter 9
“Temperature alarming function”.)
