Initial Operation

Protect the measuring tool against mois-
ture and direct sun irradiation.
Do not expose the measuring tool to ex-
treme temperatures or variations in tem-
perature.
Switching On and Off
To switch on the measuring tool, briefly press
the On/Off button 13 or measuring button 9.
When switching on the measuring tool, the laser
beam is not switched on yet.
To switch off the measuring tool, press the
On/Off button 13 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 automatic 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 measurement mode. Other measuring
modes can be switched to by pressing the re-
spective function/mode button (see "Measuring
Functions", page 18).
After switching on, the rear edge of the measur-
ing tool is preset as the reference level for the
measurement. To change the reference level,
see "Selecting the Reference Level", page 18.
Upon selection of the measuring function and
the reference level, all further steps are carried
out by pushing the measuring button 9.
With the reference level selected, place the
measuring tool against the desired measuring
line (e.g. a wall).
Briefly press the measuring button 9 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. Briefly
press the measuring button 9 again to initate
the measurement.
In the continuous measurement mode, the
measurement begins immediately upon switch-
ing on the function.
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.
Selecting the Reference Level
(see figure B–C)
For the measurement, it is possible to select
between two different reference levels:
– For measurements starting from the rear
edge of the measuring tool (e.g., when
placing against a wall), press button 12.
– For measurements starting from the front
edge of the measuring tool (e.g., when meas-
uring from onward from a table edge), press
button 1.
The selected reference level is indicated on the
display. Each time after switching on the meas-
uring tool, the rear end of the measuring tool is
preset as the reference level.
