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 0.15 mm/m for distances
above 30 m
**** applies for 100 % target reflectivity, background illumi-
nation of approximately 30'000 lux
For accurate indirect results, the use of a
tripod is recommended.
