level has now been recalibrated for this sur-
face.
gAfterwards 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 1faces downward and
the display 5faces you. Place the digital
level onto the horizontal surface. Wait for
10s.
hThen press the “Cal” calibration button 10
until “CAL1” appears briefly on the display.
Then the measuring value will flash on the
display.
iTurn the digital level 180° around the ver-
tical axis so that the spirit level still faces
downward but the display 5is facing away
from you. Wait for 10s.
jThen 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 Oand 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.
cSwitch the digital level on and place it
against the vertical surface so that the
spirit level 6faces upward and the display
5faces you. Wait for 10s.
dThen press the “Cal” calibration button 10
until “CAL1” appears on the display. Then
the measuring value will flash on the dis-
play.
eTurn the digital level 180° around the ver-
tical axis so that the spirit level still faces
upward, but the display 5faces away from
you. Wait for 10s.
fThen 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.
gAfterwards 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 6fac-
es downward and the display 5faces you.
Place the digital level against the vertical
surface. Wait for 10s.
hThen press the “Cal” calibration button 10
until “CAL1” appears on the display. Then
the measuring value will flash on the dis-
play.
iTurn the digital level 180° around the ver-
tical axis so that the spirit level still faces
downward but the display 5is facing away
from you. Wait for 10s.
jThen press the “Cal” calibration button 10
again. “CAL2” will be shown briefly on the
display. Then the measuring value (no lon-
ger flashing) will appear on the display. The
digital level has now been recalibrated for
both vertical surfaces.
Note: If the digital level is not turned around
the axis shown in the figure in steps eand
i, then the calibration cannot be completed
(“CAL2” is not indicated in the display).
Changing the Unit of Measure (see figure A)
You can change between the units of measure
“°”, “%” and “IN/FT” at any time. For this, press
the button for changing the unit of measure 8
as often as required until the desired setting is
