4.1 Sighting Scope
The Sighting scope is an accessory for the thermometer. It provides a visual
indication of the target being measured. Aiming at distant targets (up to
200 feet) becomes much easier by using the Sighting scope.
4.2 Installing and Operating the Sighting Scope
1. If the sighting scope is already installed on the thermometer,
go onto step 5.
2. The sighting scope comes with a pair of mounting clamps
already attached.
3. Slide the pair of mounting clamps over the ”V“ grove of the
thermometer from back to front as shown in FIG 4-1. DO NOT remove
the protective label from the laser sight power contacts.
4. Using the two mounting screws of the clamp, tighten the sighting scope
to the pair of clamps and the thermometer.
5. Look through the sighting scope at an arm’s length. You will see
a crosshair indicating the center of the target being measured.
6. Aim at the target and pull the trigger.
Since the sighting scope mounts on top of the thermometer, the line of
sight of the thermometer does not coincide with that of the sighting
scope, as shown in Fig. 4-1. The distance between the two lines of sight
(1
11
16") becomes less critical compared to the target size when
measuring distant targets (50 feet and longer).
