The working range increases depending on how well the laser

light is reflected from the surface of the target (scattered, not
reflective) and with increased brightness of the laser point to
the ambient light intensity (interior spaces, twilight). In unfa-
vourable conditions, e.g., with extreme interior illumination or a
badly reflecting surface, the measuring range may be limited.
In unfavourable conditions, e.g., with extreme interior illumina-

tion, badly reflecting surface or the room temperature deviating
heavily from 25 °C, the maximum deviation can be up to ±7mm
per 15 m. In favourable conditions, a deviation influence of
±0.05 mm/m must be taken into account.
The measuring tool can be clearly identified with the
serial number 5 on the type plate.
