 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.
To switch off the measuring tool, press the On/Off button 8
for a few seconds.
When no button on the measuring tool is pressed for approx.
5 minutes, the measuring tool automatically switches off to
save the batteries.
When the angle is not changed for approx. 5 minutes when in
the "Grade measurement" operating mode, the measuring
tool automatically switches off to save the batteries.
When switching off automatically, all stored values are re-
tained.

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 function/mode button (see "Measuring Func-
tions", page 23).
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 10, the reference level can be
changed (see "Selecting the Reference Level", page 22).
Place the measuring tool with the selected reference 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 permanently, the meas-
urement already starts after the first actuation of the measur-
ing button 2. In continuous measurement mode, the measure-
ment starts immediately upon switching on.
Typically, the measured value appears after 0.5 and latest af-
ter 4 seconds. The duration of the measurement depends on
the distance, the light conditions and the reflection proper-
ties of the target surface. The end of the measurement is indi-
cated by a signal tone. The laser beam is switched off auto-
matically 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:
– 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 outer 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 on-
ward from a table edge),
– The centre of thread 19 (e.g. for tripod measurements).
To select the reference level, press button 10 until the re-
quested 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 meas-
uring values in the measured-value list) is not possible.
