Measuring Procedure
When the measuring tool is inserted in the
measuring rail 24, it is always in the length
measurement or grade measurement function
after switching on by pressing the measuring
button 2. Other measuring modes can be
switched to by pressing the respective func-
tion/mode button (see "Measuring Functions",
page 28).
After switching on, the rear edge of the measur-
ing tool is preset as the reference level for the
measurement. By pressing the reference level
button 10, the reference level can be changed
(see "Selecting the Reference Level", page 27).
Place the measuring tool with the selected ref-
erence plane against the desired starting point
of the measurement (e.g. a wall).
Briefly press the measuring button 2 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 2 again to initate
the measurement.
When the laser beam is switched on permanent-
ly, the measurement already starts after the first
actuation of the measuring button 2. In continu-
ous measurement mode, the measurement
starts immediately upon switching on.
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 takes place approx.
20 seconds after collimating, the measuring tool
automatically switches off to save the battery.
Selecting the Reference Level
(see figure A)
For the measurement, you can select between
four reference planes:
Bosch Power Tools
– The rear edge of the measuring tool or the
front edge of the 90° folded-out positioning
pin 9 (e.g. when measuring onward from out-
er corners),
– The tip of the 180° folded-out positioning pin
9 (e.g. when measuring from a corner),
– The front measuring-tool edge (e.g. when
measuring onward from a table edge),
– The centre of thread 19 (e.g. for tripod meas-
urements).
To select the reference level, press button 10
until the requested reference level is indicated
on the display. Each time after switching on the
measuring tool, the rear end of the measuring
tool is preset as the reference level.
Subsequent changing of the reference level for
measurements that have already been carried
out (e.g. when indicating measuring values in
the measured-value list) is not possible.
