The visibility of the laser beam depends on the ambient light levels.
The Laser Sight Module turns on only when used with the
thermometer. The module does not turn on by itself.
Since the Laser Sight Module mounts on top of the thermometer, the
line of sight of the thermometer does not coincide with that of the
Laser Sight Module, as shown in Figure 3-6. The two lines of sight
become less critical when measuring distant targets. For example,
for the OS520, at 50 feet from the target and a 5 foot diameter target
size, there is a 2.6% offset error with respect to the target size. For
close-up targets, first make sure the target fills the laser circle, then
point it with the center of the beam approximately 1

" above the
center of the target. A simple method to make infrared
measurements is to scan the laser beam across the target area
vertically and horizontally and recall measurements of maximum
for hot and minimum for cold target (compared to the background)
to obtain the correct temperature.
