Technical Data
*The typical measurement uncertainty of ± 2 mm
is valid for measurements on white, diffusive,
reflective targets up to 5 m at low ambient light
and moderate temperatures. For distances
greater than 5 m, the measurement uncertainty
could increase additionally by 0.1 mm/m. In
unfavourable conditions (such as bright sunlight,
targets with poor reflectivity, or high or low
temperatures) the measurement uncertainty
could further increase up to ± 4 mm for distances
below 5 m and additionally by roughly 0.15
mm/m for distances greater than 5 m.
