"Error" indicator 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 (8) or reception lens (9) is fogged up (e.g. due to rapid temperature change)
Corrective measure: Rub the laser beam output (8) or the reception lens (9) dry with a soft cloth
Cause: Calculated value is larger than 999999 or smaller than –999999 m/m²/m³
Corrective measure: Split the calculation into intermediate steps
Cause: The calibration of the grade measurement was not carried out in the correct order or in the correct positions
Corrective measure: Repeat the calibration according to the instructions on the display and in the operating manual
Cause: The surfaces used for calibration were not exactly aligned on a horizontal level
Corrective measure: Repeat the calibration on a horizontal surface and check the surface beforehand, if necessary, using a spirit level
Cause: The measuring tool was moved or tilted during calibration when pressing the button
Corrective measure: Repeat the calibration and hold the measuring tool still on the surface while pressing the button
