Q 1283A
Infra-Red Non Contact Thermometer
7
The meter’s field of view is 13:1, for example, if the meter is 13 inches from the target
spot, the diameter of the target must be at least 1 inch. Other distance ratios are
show below in the field of view diagram.
The object under test should be larger than the spot size calculated by the field of
view diagram. The smaller the target object is, the closer the meter should be to it
for accurate measuring.
When accuracy is critical, make sure the target is at least twice as large as the spot
size.
Distance & Spot Size:
As distance (D) from the object increases, the spot size (S) of
the area measured by the unit becomes larger.
Locating A Hot Spot:
To find a hot spot, first aim the thermometer to the outside
of the target area
, then scan across in an up and down motion until the hot spot is
located.
