Atmospheric
conditions

Measurements can be made to reflector tapes over the entire range without external
ancillary optics.
Accuracy Accuracy refers to measurements to standard prisms.
For TS50/TM50 - R1000:
Beam interruptions, severe heat shimmer and moving objects within the beam path
can result in deviations of the specified accuracy.
For MS50 - R2000:
Beam interruptions, severe heat shimmer and moving objects within the beam path
can result in deviations of the specified accuracy.
Characteristics
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
