3Laser Sighting

NOTE

The Laser Sighting turns on only when used with the thermometer. The module does not turn on by itself.

The line of sight of the thermometer does not coincide with that of the Laser Sighting, as shown in Figure 3-4. The two lines of sight become less critical when measuring distant targets. For example, at 30 feet from the target and a 3 foot diameter target size, there is a 2.7% 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" below 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.
