IR250-en-GB_V3.1 7/16 5
Field of View
As the distance from the object increases, the spot size of the area measured becomes larger. The
meter’s field of view is 6:1; in other words if the meter is 6 inches from the target (spot), the diameter
of the target must be at least 1 inch. Note that measurements should normally be made as close as
possible to the device under test. The meter can measure from moderate distances but the
measurement may be affected by external sources of light. In addition, the spot size may be so
large that it encompasses surface areas not intended to be measured.
