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 as shown in Figure 2-2. Figures 2-3
through 2-9 show the field of view vs distance for the various
thermometers.
