EN Technical Data
* applies for 100 % target reflectivity (white painted wall),
low background illumination, 25 ºC
** applies for 10 to 500 % target reflectivity, high background
illumination, - 10 ºC to + 50 ºC
*** Tolerances apply from 0.05 m to 10 m with a confidence
level of 95%. The maximum tolerance may deteriorate to
0.1 mm/m between 10 m to 30 m and to 0.20 mm/m for
distances above 30 m
**** applies for 100 % target reflectivity, background illumi-
nation of approximately 30'000 lux
***** after user calibration. Additional angle related devia-
tion of +/- 0.01° per degree up to +/-45° in each quadrant.
Applies at room temperature. For the whole operating
temperature range the maximum deviation increases by +/-
0.1°.
For accurate indirect results, the use of
a tripod is recommended. For accurate
tilt measurements a transverse tilt should be
avoided.
