The indicators for center line
mode 42 light up
continuously.
As soon as the laser beam
hits the reception area 26, a
beep sounds until the center
line is found.
The speed at which the rotation head moves
will slow down as soon as the laser beam hits
the reception area 26.
When the center line has been found, the
measuring tool automatically switches off the
center line mode. The set slope is saved and
shown on the display.
– To cancel center line mode during
the search, short press the center
line mode button 19.
or
– Simultaneously press the slope
buttons 18 and 20 to activate
automatic leveling.
Speeding Up Center Line Mode
Searching for the center line always begins
with an upward movement of the rotation
/
head. The direction of the movement can be
changed if the position of the laser receiver
above the center line is known and the laser
beam is not yet in the reception area.
– Press the center line mode button
19 for approx. 2 s.
Automatic upward and downward
movement of the rotation head
starts.
– Press the slope button 20.
The rotation head is moved
downwards.
Anti-Drift System (ADS)
The measuring tool has an anti-drift
system; after position changes or shock to
the measuring tool, or in case of ground
vibrations, it keeps the measuring tool from
leveling in at changed heights, and thus
prevents vertical errors.
The anti-drift system is activated
approx. 30 s after the measuring tool
2610A16816.indd 24
has been switched on.
During activation the shock-warning indicator
38 flashes slowly. The indicator lights up
continuously after activation.
If the vertical position of the measuring tool
is changed or a severe shock is registered,
then the anti-drift system is triggered: the
rotation of the laser is stopped and the shock-
warning indicator 38 flashes. In addition, a
beep sounds for 5 s on the laser receiver.
– Press the On/Off button 17 briefly
when the anti-drift system is
triggered.
Automatic leveling starts (see
"Automatic Leveling during
Operation", page 22).
– Now check the height of the laser beam
against a reference point and correct the
height of the measuring tool if necessary.
Deactivating the Anti-Drift System
The anti-drift system can be deactivated
during operation of the measuring tool.
– Press the On/Off button 17.
The anti-drift system is deactivated.
The shock warning indicator 38 is
no longer displayed.
This setting is not saved when the tool is
switched off. The measuring tool always
starts with the anti-drift system activated.
Line Control in Vertical Mode
(GRL 500 HV)
When the measuring tool is in the vertical
mode, you can position the rotational plane
around the Y-axis for simple alignment or
parallel alignment.
– To turn the rotational plane
clockwise, press the slope button
18; to turn it counterclockwise,
press the slope button 20.
Positioning is possible within a range of
±8.5%.
The speed at which the rotation head moves
begins slowly and continually increases.
Center Line Mode in Line Control
(see figure E)
In center line mode, the measuring tool
automatically tries to find the center line by
