3. The target temperature and emissivity are displayed on the LCD.
Determine the emissivity of the target (refer to Appendix B). Press the
decrement the target emissivity.
4. Press the
on the display. This allows the thermometer to operate continuously
whether or not the trigger is pulled. To unlock the trigger, press the
LOCK
displayed. When the trigger is pulled, the Laser Sighting as well as the
display backlight will stay on .
5. After completing a temperature measurement, release the trigger.
In order to conserve battery life, the thermometer goes into sleep
mode and the Laser Sighting turns off.

2.2.1 Measurement Techniques

You can use the IR Thermometer to collect temperature data in any
one of five different ways:
• Spot Measurement — Measures the temperature of discrete objects
such as motor bearings, engine exhaust manifolds, etc.:
1.
2.
3.
• Differential Measurement — Measures the temperature differential
between two spots (the maximum and minimum temperatures
viewed)
