"Error" indicator and "----" in the display

Cause: Angle between laser beam and target is too sharp

Corrective measure: Increase the angle between the laser beam and target

Cause: Target surface is reflecting too strongly (e.g. mirror) or too weakly (e.g. black material), or ambient light is too bright.

Corrective measure: To help with targeting, use an object that is as lightly coloured as possible (e.g. a sheet of bright white paper).

Cause: Laser beam output (13) or reception lens (12) is fogged up (e.g. due to rapid temperature change)

Corrective measure: Rub the laser beam output (13) or the reception lens (12) dry with a soft cloth

Cause: Calculated value is larger than 999,999 or smaller than –999,999 m/m²/m³

Corrective measure: Split the calculation into intermediate steps
