easuring range (with target plate)

0.2 … 70 m

Accuracy

ypically ±1.5 mm for single and continuous

measurement **

** Atmospheric influences interfere with distance measurements. Over long

distances, an influence of ± 1.5 mm + 20 ppm of the measured distance is

to be expected. Typical accuracy: 2 Sigma at 25 ⁰C.
