"ERROR" in the Display

"ERROR" indicator in the display

Cause: Addition/subtraction of measured values with different units of measurement

Corrective measure: Add/subtract only measured values with the same units of measurement

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 strong

Corrective measure: Use a laser target plate (accessory)

Cause: Laser beam output (21) or reception lens (20) is fogged up (e.g. due to rapid temperature change)

Corrective measure: Rub the laser beam output (21) or the reception lens (20) dry with a soft cloth

Cause: Calculated value is larger than 1 999 999 or smaller than -999 999 m/m²/m³

Corrective measure: Split the calculation into intermediate steps
