What does the displayed message E 255 mean?
The return signal is too weak, measuring times are too long. The measured distance must be more than 250mm. Use a target plate to reduce measuring times.
What does the displayed message E 256 mean?
The return signal is too strong. If using target plates, the white side should be used for measuring short distances.
What does the displayed message E 272 and E 288 mean?
Turn the instrument off and on again. If the messages continue to be displayed, the instrument has to be sent in for servicing, as there is an internal module error in the electronics. Please contact your dealer nearby.
