Accuracy Check
Regularly check the accuracy of the grade measurement and distance measurement.
Accuracy Check and Calibration of the Grade Measurement
To do this, lay the measuring tool on a table and measure the inclination.
Turn the measuring tool by 180° and measure the inclination again.
The difference between the displayed values must not exceed 0.3°.
In case of greater deviation, the measuring tool must be recalibrated.
Press and hold the

menu.
Select
and confirm the selection with the
button.
Follow the instructions on the display.
After strong temperature changes and after knocks, we recommend an accuracy
check and, if necessary, calibration of the measuring tool. After a temperature vari-
ation, the measuring tool must adjust to the ambient temperature for a while before calib-
ration is performed.
Accuracy check of the distance measurement
For the accuracy check, the measurement should be taken under favourable conditions,
i.e. the measuring section should be indoors and the target surface for the measurement
should be smooth and reflect well (e.g. a white-painted wall).
Select a measuring section of approx.
3
to
10
m long, the length of which you know ex-
actly (e.g. room width, doorway).
