Würth WDM5-12
* 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 0.2 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 temper-
ature range the maximum deviation increases by +/- 0.1°.
****** after calibration (the compass can not be used for
navigation)
For accurate indirect results, the use of a
i
tripod is recommended. For accurate tilt
measurements a transverse tilt should be
avoided.
