* The typical measurement uncertainty of ± 3 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.
