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.
