Rotate the measuring tool by 180°
around the vertical axis (as shown in
figure D). Wait again for 10 s and note
down the second measured value.
Calibrate the measuring tool
only when the difference ∆
between both reading values is
greater than 0.1°.
Calibrate the measuring tool in the
position (vertical or horizontal), in
which the difference of the measured
values has been determined.
Calibration for Horizontal
Surfaces (see figure E)
The surface onto which you place the
measuring tool must not deviate from
the horizontal line by more than 5°. If
the deviation is greater, the calibration
process is discontinued with the indi-
cation "---" .
Switch the measuring tool on and
place it onto the horizontal surface in
such a manner that the spirit level 2
faces upward and the display 6 faces
you. Wait for 10 s.
Then press the "Calibrate" func-
tion button 9 until "CAL1" is briefly
indicated in the display. Afterwards the
measured value flashes in the display.
Turn the measuring tool by 180°
around the vertical axis so that the
spirit level still faces upward, but the
display 6 faces away from you. Wait for
10 s.
Then press the "Calibrate" func-
tion button 9 again. "CAL2" is briefly
indicated in the display. Afterwards the
measured value appears in the display
(no longer flashing). The measuring
tool is now newly calibrated for this
surface.
Afterwards you must calibrate the
measuring tool for the opposite sur-
face. For this, turn the measuring tool
around its horizontal axis in such a
manner that the spirit level 2 faces
downward and the display 6 faces you.
Place the measuring tool onto the hor-
izontal surface. Wait for 10 s.
Then press the "Calibrate" func-
tion button 9 until "CAL1" is briefly
indicated in the display. Afterwards the
measured value flashes in the display.
