Distance&SpotSize
As the distance (D) from the object increases, the spot size (S) of the area
measured becomes larger. The meter’s D:S ratio is 20:1, so at 20 inches (508mm),
the diameter of the target being measured must be at least 1” (25.4mm).
The lasers converge at 10” (254mm) to pinpoint the optimized measuring point.
