The meter's field of view is 8:1. For example, if the meter is 16 inches from the target
(spot), the diameter of the target must be at least 2 inches. Other distance ratios are
shown below in the field of view diagram.
Note that measurements should normally be made less than 2 feet from the target. The
meter can measure from further 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.
