Technical Data Zoom90 | 45
8 Technical Data
8.1 Angle Measurement
Accuracy
Characteristics Absolute, continuous, diametric.
8.2 Distance Measurement with Reflectors
Range
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.
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.
