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, press the trigger to turn on the unit, and then 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) or MAX-MIN (span).
5.
Press the °C/°F button to change the unit of measure.
6.
To measure the ambient temperature, just press “Tamb” key, and then press the trigger down
and keep, you can get the measurement result from LCD directly. After releasing trigger, LCD will
hold the measurement result.
