LOCATING A HOT OR COLD SPOT

To find a hot or cold spot, aim the Thermometer outside the target area. Then, slowly scan across
the area with an up and down motion until you located the hot or cold spot. See Figure 5.

DISTANCE AND SPOT SIZE

As the distance (D) from the target being measured increases, the spot size (S) of the area
measured by the unit becomes larger. The spot size indicates 90% encircled energy. The maximum
D:S is obtained when the Thermometer is 600mm (60 in) form the target resulting in a spot size of
20mm (2 in). See Figure 6.
