Measurements can be made to reflector tapes over the entire range without
external ancillary optics.
Accuracy refers to measurements to standard prisms.

with lock
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.
