Troubleshooting
Temperature Warning
Temperature warning flashes, measurement not possible
Cause:
Measuring tool is outside the operating temperature of –10 °C to +45 °C (in the
continuous measurement function up to +40 °C)
Corrective measure:
Wait until the measuring tool reaches the operating temperature
"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 measure-
ment
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 ma-
terial), or ambient light is too strong
Corrective measure:
Use a laser target plate (accessory)
Cause:
Laser beam output
(19)
or reception lens
(18)
is fogged up (e.g. due to rapid tem-
perature change)
Corrective measure:
Rub the laser beam output
(19)
or the reception lens
(18)
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
Calibration
"CAL" indicator and "ERROR" indicator in the display
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
