* favourable conditions are: white and diffuse reflecting target
(white painted wall), low background illumination 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 0.2 m to 5 m with a confidence
level of 95%.
With favourable conditions the tolerance may deteriorate by
0.1 mm/m for distances above 5 m.
With unfavourable conditions the tolerance may deteriorate
by 0.15 mm/m for distances above 5 m.
