* favourable conditions are: white and diffuse reflecting target (white painted wall), low background illu-
mination and moderate temperatures.
** unfavourable conditions are: targets with lower or higher reflectivity or high background illumination or
temperatures at the upper or lower end of the specified temperature range.
*** Tolerances apply from 0.05 m to 10 m with a confidence level of 95%.
With favourable conditions the tolerance may deteriorate by 0.10 mm/m for distances above 10 m.
With unfavourable conditions the tolerance may deteriorate by 0.15 mm/m for distances above 10 m.
**** after user calibration. Additional angle related deviation of +/-0.01° per degree up to +/-45° in each quad-
rant.
Applies at room temperature. For the whole operating temperature range the maximum deviation
increases by +/-0.1°.
