Find a Hot or Cold Spot
To find a hot or cold spot, aim the Product outside the
necessary area. Then, slowly scan across the area with an up
and down motion until the hot or cold spot is found.
Distance and Spot Size
As the distance (D) from the object under measurement
increases, the spot size (S) of the area measured by the
Product becomes larger. The relationship between distance and
spot size (D:S) is shown in Figure . The spot sizes indicate 90 %
encircled energy.
