2.2 Operating the Thermometer

1a. (Without the Laser Sighting) -Aim the thermometer at the target to be measured. Use the “V” groove (shown in Figure 1-1) on top of the thermometer to align the target to the thermometer’s field of view. Look down the “V” groove with one eye only, in order to guarantee proper sighting. Pull and hold the trigger.

1b. (With the Laser Sighting) - Set the laser power switch to the ON position. Aim at the target and pull the trigger. The laser beam and the red power indicator LED will turn on while the trigger is pulled. Refer to Chapter 3 for more details on the Laser Sighting.

2.The field of view of the thermometer should fall within the area

of the target being measured. See Figure 2-3. Figures 2-4 through 2-6 show the field of view vs distance for the various thermometers.
