Distance to Spot Size Ratio
The distance-to-spot ratio of the infrared thermometer is
20:1. This means that the spot diameter at a distance of 20
inches is 1 inch (25.4 mm). To measure a smaller spot area,
move the thermometer closer to the target and use the
distance-to-spot ratio of 20:1 to estimate the spot size. For
instance, at a target distance of 10 inches, the spot size is
0.5 inch (12.7 mm). The further away the target, the greater
the spot size. Make sure the target area you want to
measure is larger than the spot size.
