Operating Modes - CST/BERGER LM800 Serie Manual Original

The measuring tool immediately starts the automatic
levelling after switching on. During the coarse level-
ling, the laser flashes in point operation. After comple-
tion of the coarse levelling, the laser beam lights up
continuously and the measuring tool automatically
starts in the last stored operating mode after switch-
ing off. The measuring tool precisely levels itself within
the next 60 s.
When factory set, the shock-warning function is auto-
matically switched on, and the shock-warning indica-
tor 9 lights up red.
To switch off, press the On/Off button 4 for at least
3 seconds until the shock-warning indicator 9 and the
"working without automatic levelling indicator" 7 flash.

Operating Modes

Course of X- and Y-Axis
The X- and Y-axis are marked on the housing next to
the rotation head. The alignment aide 15 facilitates the
alignment of the measuring tool alongside the Y-axis.
Rotational Operation (LM800GR)
The measuring tool exclusively operates with fixed
rotational speed in rotational operation, which is also
suitable for use of a laser receiver.
Overview (LM800DP)
All three operating modes are possible with the meas-
uring tool in horizontal and vertical position.
Rotational Operation
Rotational operation is especially
recommended when using the
laser receiver. You can select
between
speeds.
Line Operation
In this operation mode, the variable
laser beam moves within a limited
aperture angle. This increases the
visibility of the laser beam in com-
parison to rotational operation. You
can select between different aper-
ture angles.
Point Operation
This operation mode enables the
best visibility of the variable laser
beam. As an example, it is used for
easy projecting of heights or
checking building lines.
Rotational Operation, Point Operation
(600/300/150 min
To switch to rotational operation, press the rotational
operation button 23. Rotational operation starts with
the last set or highest rotational speed.

-1 -1
, 0 min ) (LM800DP)
To change the rotational speed, press the rotational
operation button 23 again. The rotational speed is
decreased each time after pressing the button. After
the lowest rotational speed, the measuring tool
switches to point operation. Pressing button 23 again
takes you back to rotational operation with the highest
rotational speed.
When working with the laser receiver, the highest
rotational speed should be set. When working without
laser receiver, reduce the rotational speed for
improved visibility of the laser beam and use the laser
viewing glasses 26.
Line Operation,
(10°/45°/90°/180°, 0°) (LM800DP)
To switch to line operation, press the line operation
button 22. The measuring tool starts with the smallest
aperture angle.
To change the aperture angle, press the line operation
button 22. The aperture angle is increased in steps.
After the largest aperture angle, the measuring tool
switches to point operation. Pressing button 22 again
takes you back to line operation with the smallest
aperture angle.
Note: Due to inertia, it is possible for the laser to
slightly move beyond the end point of the laser line.
Switching the Bottom Plumb Beam On and Off
(LM800DP)
To switch the bottom plumb beam on or off, briefly
(less than 3 seconds) press the On/Off button 4.
Rotating the Laser Point/Laser Line in the Rota-
tional Plane (LM800DP)
In horizontal and vertical position of the measuring
tool, the laser point or the laser line can be rotated in
steps by 360° within the rotational plane. Press but-
ton 21 to rotate in clockwise direction, and button 20
to rotate in anticlockwise direction. Pressing and hold-
ing the buttons increases the speed of the rotation
head in the desired direction.
Aligning the Rotational Plane in the Vertical
Position (LM800DP)
When the measuring tool is in the vertical position and
in rotational operation, it is possible to rotate the rota-
tional plane around the Y-axis for easy sighting out or
parallel alignment. For this, press the button for rota-
tion in clockwise direction 21 or the button for rotation
in anticlockwise direction 20.
With the remote control 30, it is also possible to rotate
the laser point or the laser line around the Y-axis.
Rotation is possible within a range of ± 10 %.
