Switching On and Off
To switch on the measuring tool, briefly press the On/Off
button 7 or measuring button 12. When switching on the meas-
uring tool, the laser beam is not switched on yet.
To switch off the measuring tool, press the On/Off button 7 for
a few seconds.
If none of the measuring tool buttons are pressed for approx.
5 minutes, the measuring tool switches off automatically in
order to extend the service life of the battery.
When a measured value has been stored, it is retained in auto-
matic switch-off mode. When switching on the measuring tool
again, "M" is indicated in the display.
Measuring Procedure
After switching on, the measuring tool is in the length measure-
ment mode. Other measuring modes can be switched to by
pressing the respective function/mode button (see "Measuring
Functions", page 28).
After switching on, the rear edge of the measuring tool is pre-
set as the reference level for the measurement. To change the
reference level, see "Selecting the Reference Level", page 28.
Upon selection of the measuring function and the reference
level, all further steps are carried out by pushing the measuring
button 12.
With the reference level selected, place the measuring tool
against the desired measuring line (e.g. a wall).
Push the measuring button 12 to switch on the laser beam.
Do not point the laser beam at persons or animals and
do not look into the laser beam yourself, not even from a
large distance.
Aim the laser beam at the target surface. Push the measuring
button 12 again to initiate the measurement.
In the tracking function, the measurement already starts upon
first actuation of the measuring button 12.
Typically, the measured value appears after 0.5 and latest after
4 seconds. The duration of the measurement depends on the
distance, the light conditions and the reflection properties of
the target surface. The end of the measurement is indicated by
a signal tone. The laser beam is switched off automatically
upon completion of the measurement.
When no measurement has taken place approx. 20 seconds
after sighting, the laser beam is switched off automatically to
save the batteries.
