Temperature

Locating a Hot Spot

To find a hot spot aim the thermometer outside the
area of interest, then scan across with an up and
down motion until you locate the hot spot.

Field of View

Make sure that the target is larger than the unit's spot
size. The smaller the target, the closer you should be
to it. When accuracy is critical, make sure the target
is at least twice as large as the spot size.
Distance & Spot Size
