Select the unit of measure "°" (see "Changing the Unit of Meas-
ure", page 19).
Wait for 10 s and note down the measured value.
Rotate the measuring tool by 180° around its vertical axis. 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 hori-
zontal), in which the difference of the measured values has
been determined.
Calibration for Horizontal Surfaces (see figure F)
The surface onto which you place the measuring tool must not
deviate from the horizontal line by more than 5°. If the devia-
tion is greater, the calibration process is discontinued with the
indication "---" .
Switch the measuring tool on and position it on the hori-
zontal surface in such a manner that the spirit level 1 faces
upward and the display 7 faces you. Wait for 10 s.
Then press the "Cal" calibration button 20 for approx.
2 seconds until "CAL1" appears briefly on the display.
Then the measuring value will flash on the display.
Turn the measuring tool by 180° around the vertical axis
so that the spirit level still faces upward, but the display 7
faces away from you. Wait for 10 s.
Then press the "Cal" calibration button 20 again. "CAL2"
will be shown briefly on the display. Then the measuring
value (no longer flashing) will appear on the display. The
measuring tool has now been recalibrated for this sup-
porting surface.
After this, the measuring tool must be calibrated for the
opposite supporting surface. Rotate the measuring tool
around the horizontal axis in such a manner that the spirit
level 1 faces downward and the display 7 faces you. Place
the measuring tool on the horizontal surface. Wait for
10 s.
Then press the "Cal" calibration button 20 for approx.
2 seconds until "CAL1" appears briefly on the display.
Then the measuring value will flash on the display.
Turn the measuring tool 180° around the vertical axis so
that the spirit level still faces downward but the display 7
is facing away from you. Wait for 10 s.
Then press the "Cal" calibration button 20 again. "CAL2"
will be shown briefly on the display. Then the measuring
value (no longer flashing) will appear on the display. The
measuring tool has now been recalibrated for both hori-
zontal supporting surfaces.
Note: If the measuring tool is not turned around the axis shown
in the figure in steps and , then the calibration cannot be
completed ("CAL2" is not indicated in the display).
Calibration for Vertical Surfaces (see figure G)
The surface onto which you place the measuring tool must not
deviate from the vertical 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 position it on the verti-
cal surface in such a manner that the spirit level 8 faces
upward and the display 7 faces you. Wait for 10 s.
Then press the "Cal" calibration button 20 for approx.
2 seconds until "CAL1" appears briefly on the display.
Then the measuring value will flash on the display.
Turn the measuring tool by 180° around the vertical axis
so that the spirit level still faces upward, but the display 7
faces away from you. Wait for 10 s.
Then press the "Cal" calibration button 20 again. "CAL2"
will be shown briefly on the display. Then the measuring
value (no longer flashing) will appear on the display. The
measuring tool has now been recalibrated for this sup-
porting surface.
After this, the measuring tool must be calibrated for the
opposite supporting surface. Rotate the measuring tool
around the horizontal axis in such a manner that the spirit
level 8 faces downward and the display 7 faces you. Place
the measuring tool against the vertical surface. Wait for
10 s.
Then press the "Cal" calibration button 20 for approx.
2 seconds until "CAL1" appears briefly on the display.
Then the measuring value will flash on the display.
Turn the measuring tool 180° around the vertical axis so
that the spirit level still faces downward but the display 7
is facing away from you. Wait for 10 s.
