Atmospheric
conditions
Accuracy For TS50/TM50 - R1000:
Object in shade, sky overcast. 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.
For MS50 - R2000:
Object in shade, sky overcast. 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.
