Shortest measuring distance: 1.5 m
Range A: Strong haze, visibility 5 km; or strong sunlight, severe heat shimmer
Range B: Light haze, visibility about 20 km; or moderate sunlight, slight heat
shimmer
Range C: Overcast, no haze, visibility about 40 km; no heat shimmer
Measurements can be made to reflector tapes over the entire range without external
ancillary optics.
Accuracy refers to measurements to standard prisms.

*1 does not include radio transfer time to the CS.
Beam interruptions, severe heat shimmer and moving objects within the beam path
can result in deviations of the specified accuracy.
The display resolution is 0.1 mm.
