8.3 Distance Measurement without Reflectors
Range
Atmospheric conditions
Accuracy
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.
Characteristics
Laser dot size
8.4 Distance Measurement - Long Range (LO mode)
Range The range of the long range measurements is the same for A5 and A10.
Atmospheric conditions
Accuracy
Beam interruptions, severe heat shimmer and moving objects within the beam path can result in devia-
tions of the specified accuracy. The display resolution is 0.1 mm.
