Display Notices
All display notices are indicated by "InFo" or "Error".
The following errors can be corrected.
Technical Specifications
* in favourable conditions (optimal target surface, room
temperature) up to 12 m. In unfavourable conditions, such as
intensive sunshine, very weakly reflecting target surface or
large temperature fluctuations, measuring accuracy may
deteriorate to approx. ± 0.25 mm/m for distances above
12 m.
InFo Cause Correction
252 Temperature too
high Let device cool down.
253 Temperature too low Warm device up
255 Received signal too
weak, time for a
measurement too
long. Use a target plate
256 Received signal too
strong Use a target plate
(gray side)
257 Faulty measurement,
too much back-
ground light Use a target plate
(brown side)
Error Cause Correction
