Measuring Procedure
After switching on, the measuring tool is always in length
measurement or continuous measurement mode. Other
measuring modes can be switched to by pressing the respec-
tive mode button (see "Measuring Functions", page 19).
After switching on, the rear edge of the measuring tool is pre-
set as the reference level for the measurement. By pressing
the reference level button 8, the reference level can be
changed (see "Selecting the Reference Level
(see figures A – E)", page 19).
Upon selection of the measuring function and the reference
level, all further steps are carried out by pushing the measur-
ing button 7.
With the reference level selected, place the measuring tool
against the desired measuring line (e.g. a wall).
Briefly press the measuring button 7 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 7 again to initate the measurement.
When the laser beam is switched on permanently, the meas-
urement already starts after the first actuation of the measur-
ing button 7. In continuous measurement mode, the measure-
ment starts immediately upon switching on.
The measured value typically appears after 0.5 seconds and
at the latest after 4 seconds. The duration of the measure-
ment depends on the distance, the light conditions and the re-
flection properties of the target surface. The end of the meas-
urement is indicated by a signal tone. The laser beam is
switched off automatically upon completion of the measure-
ment.
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 figures A – E)
For measuring, you can select between four different refer-
ence planes:
– The rear edge of the measuring tool or the front edge of the
laterally folded-out positioning pin 18 (e.g. when measur-
ing onward from outer corners),
– The tip of the folded-out positioning pin 18 (e.g. when
measuring from a corner),
– The front measuring-tool edge (e.g. when measuring on-
ward from a table edge),
– The thread 21 (e.g. for tripod measurements).
To select the reference level, press button 8 until the request-
ed reference level is indicated on the display. Each time after
switching on the measuring tool, the rear end of the measur-
ing tool is preset as the reference level.
Subsequent changing of the reference level for measure-
ments that have already been carried out (e.g. when indicat-
ing measuring values in the measured-value list) is not possi-
ble.
Bosch Power Tools
Continuous Laser Beam
If required, the measuring tool can also be switched to the
continuous laser beam mode. For this, push the button for
continuous laser beam 2. "LASER" lights up continuously in
the display.
 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.
In this setting, the laser beam also remains switched on be-
tween measurements; for measuring, it is only required to
press the measuring button 7 once.
To switch off the continuous laser beam, press button 2 again
or switch the measuring tool off.
Switching off the continuous laser beam during a measure-
ment automatically ends the measurement.
Display Illumination
The display illumination is switched on and off by pressing
button 11. When no button is pressed 10 s after switching on
the display illumination, it is switched off to save the batter-
ies.
Audio Signal
To switch the audio signal on and off,
press the function-mode button 3 un-
til the "audio-signal adjustment" indi-
cation appears on the display. Select
the required setting by pressing the
plus button 6 or the minus button 12.
The selected audio-signal adjustment
is retained when switching the measuring tool off and on.
Changing the Unit of Measure
For indication of the measured values, the unit of measure can
be changed at any time.
The following units of measure are possible:
– Length measurement: m, cm, mm,
2
– Area/surface measurement: m
3
– Volume measurement: m .
To to change the unit of measure,
press the function-mode button 3 un-
til the "change unit of measure" indi-
cation appears on the display. Select
the required unit of measure by
pressing the plus button 6 or the mi-
nus button 12.
