ations in temperature. As an example, do not leave it in
vehicles for a long time. In case of large variations in tem-
perature, allow the anglefinder/digital level to adjust to
the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the anglefinder/digital level can be
impaired.

recommended to carry out an accuracy check (see "Ac-
curacy Check and Calibration of the Anglefinder/digital
level", page 22) each time before continuing to work.
must be clean. Protect the anglefinder/digital level
against impact and shock. Debris particles or deforma-
tions can lead to faulty measurements.
Do not leave the switched-on anglefinder/digital level
unattended and switch the anglefinder/digital level off
after use. Other persons could be blinded by the laser
beam.
Press the "ON/OFF" switch 14 to switch the anglefinder/
digital level on or off.
If the "H" indicator lights up, the value from the last
measurement is still saved. This value can be deleted by
briefly pressing the "ON/OFF" button 14.
The anglefinder/digital level will shut down after approx.
30 minutes of inactivity to preserve battery life.
The anglefinder/digital level can be aligned horizontally
with spirit level 9 and vertically with spirit level 10.
When you rotate the measuring device 180°, the display
will also rotate automatically to make the displayed value
easier to read.
After switching on, the anglefinder/digital level is always
in normal measuring mode.
In "Normal Measuring" mode, angle measurement and
grade measurement are carried out simultaneously.
Angle Measurement Operating Mode
The anglefinder/digital level is in the "Angle Measure-
ment" operating mode every time it is switched on.
Measuring Angles (see figures C–D)
Place the fold-out leg 1 and the base leg 4 flat on the
surfaces around the angle you wish to measure.
measured angle value w will display on the display 7 as
measured value c. The measured value will remain on the
display until the angle between fold-out leg 1 and base
leg 4 has changed.
Transferring Angles (see figure E)
Once you have your desired angle measurement (see
Measuring Angles section), lock the position of the legs
by tightening the locking wheel 3.
Place the anglefinder/digital level in the desired position
against the workpiece. Use the legs as a straight edge to
transfer the angle.
Press the "HOLD" memory button 17 to save the current
measuring value. The a indicator will flash on the display
as confirmation. The currently displayed value is frozen
and will not change even when the leg is moved. If you
press the "HOLD" memory button again, the a indicator
will permanently be shown on the display. The displayed
value will change if you move the legs. The previously fro-
zen value is now saved in the background. If the "HOLD"
memory button 17 is pressed again, the previously saved
value is displayed and the a indicator flashes.
The unit can only store one value at a time. Storing a new
value will automatically overwrite the previously stored
value.
