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.
