The battery charge-control indicator
g
indicates the charging
progress. During the charging procedure, the segments flash
one after the other. When all segments of battery charge-con-
trol indicator
g
are displayed, the battery is completely
charged.
Disconnect the battery charger from the mains supply when
not using it for longer periods.
The measuring tool cannot be used during the charging proce-
dure.
Protect the battery charger against moisture!
Recommendations for Optimal Handling of the Battery
Store the battery only when within the allowable temperature
range, see “Technical Data”. As an example, do not leave the
battery in a vehicle in summer.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
Operation
Initial Operation
Do not leave the switched on measuring tool unattend-
ed and switch the measuring tool off after use.
Other
persons could be blinded by the laser beam.
Protect the measuring tool against moisture and direct
sun light.
Do not subject the measuring tool to extreme tempera-
tures or variations in temperature.
As an example, do
not leave it in vehicles for long time. In case of large varia-
tions in temperature, allow the measuring tool to adjust to
the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
Avoid heavy impact to or falling down of the measuring
tool.
After severe exterior effects to the measuring tool, it
is recommended to carry out an accuracy check (see “Ac-
curacy Check and Calibration of the Grade Measurement”
and “Accuracy Check of the Distance Measurement” on
page 25) each time before continuing to work).
Switching On and Off
For
switching on
the measuring tool, the following possibili-
ties are given:
– Pressing the On/Off button
8
: The measuring tool is
switched on and is in length measurement mode. The laser
is not activated.
– Pressing the measuring button
2
: Measuring tool and laser
are switched on. The measuring tool is in length measure-
ment mode. When the measuring tool is inserted in the
measuring rail
24
, the grade measurement function is acti-
vated.
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.
To save energy, only switch the measuring tool on when you
are using it.
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 22).
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 21).
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 on-
ward 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).
