level has now been recalibrated for this sur-
face.

Afterwards you must calibrate the digital
level for the opposite surface. For this, turn
the digital level around its horizontal axis so
that the spirit level
1
faces downward and
the display
5
faces you. Place the digital
level onto the horizontal surface. Wait for
10s.
h
Then press the
“Cal”
calibration button
10
until
“CAL1”
appears briefly on the display.
Then the measuring value will flash on the
display.
i
Turn the digital level 180° around the ver-
tical axis so that the spirit level still faces
downward but the display
5
is facing away
from you. Wait for 10s.
j
Then press the
“Cal
” calibration button
10
again.
“CAL2”
will be shown on the display.
Then the measuring value (no longer flash-
ing) will appear on the display. The digital
level has now been recalibrated for both
horizontal surfaces.
Note:
If the digital level is not turned around
the axis shown in the figure in steps
O
and
S
,
then the calibration cannot be completed
(
“CAL2”
is not indicated in the display).
Calibration for Vertical Surfaces
(see figure D)
The vertical surface used to calibrate the tool
cannot slope more than 5°. If the slope is
greater than 5°, the calibration is discontinued
and
“---”
will display.
c
Switch the digital level on and place it
against the vertical surface so that the
spirit level
6
faces upward and the display
5
faces you. Wait for 10s.
d
Then press the
“Cal”
calibration button
10
until
“CAL1”
appears on the display. Then
the measuring value will flash on the dis-
play.
e
Turn the digital level 180° around the ver-
tical axis so that the spirit level still faces
upward, but the display
5
faces away from
you. Wait for 10s.
f
Then press the
“Cal”
calibration button
10
again.
“CAL2”
will be shown on the display.
Then the measuring value (no longer flash-
ing) will appear on the display. The digital
level has now been recalibrated for this sur-
face.

Afterwards you must calibrate the digital
level for the opposite surface. For this, turn
the digital level around its horizontal axis
in such a manner that the spirit level
6
fac-
es downward and the display
5
faces you.
Place the digital level against the vertical
surface. Wait for 10s.
