Operating Modes; Automatic Levelling - CST/BERGER RL25H Manual Original

Stand-by-operation with Storage of the Operating Mode
With the remote control 26, the measuring tool can be switched
to stand-by-operation for 2 hours (max.). In standby operation,
the levelling indicator 3 flashes slowly; all other indicators and
the laser are switched off.
The operating mode set on the measuring tool is retained. When
the shock-warning function is switched on, the position of the
measuring tool is also monitored during standby operation.
To end standby operation, press any button of the measuring
tool or the remote control 26.

Operating Modes

Course of X- and Y-Axis
The course of the X- and Y-axis is marked on the housing above
the rotation head.
Rotational Operation (RL25H)
The measuring tool exclusively operates with fixed rotational
speed in rotational operation, which is also suitable for use of a
laser receiver.
Overview (RL25HV)
All three operating modes are possible with the measuring tool
in horizontal and vertical position.
Rotational Operation
Rotational operation is especially recom-
mended when using the laser receiver. You
can select between different rotational
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 comparison to rotational
operation. You can select between differ-
ent aperture angles.
Point Operation
This operation mode enables the best visi-
bility of the variable laser beam. As an ex-
ample, it is used for easy projecting of
heights or checking building lines.
Rotational Operation, Point Operation (RL25HV)
(600/300/150 min
Each time after switching on, the measuring tool is in rotational
operation with the highest rotational speed.
To switch from line operation to rotational operation, press the
rotational operation button 4. Rotational operation starts with
the highest rotational speed.
To change the rotational speed, press the rotational operation
button 4 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 4
takes you back again 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, re-
duce the rotational speed for improved visibility of the laser
beam and use the laser viewing glasses 27.
Line Operation (RL25HV)
(10°/25°/50°)
To switch to line operation, press the line operation button 5.
The measuring tool starts with the smallest aperture angle.
To change the aperture angle, press the line operation button 5.
The aperture angle is increased in two steps. Pressing button 5
again takes you back to line operation with the smallest aper-
ture angle.
Note: Due to inertia, it is possible for the laser to slightly move
beyond the end point of the laser line.
Rotating the Laser Point/Laser Line in the Rotational Plane
(RL25HV)
When automatic levelling is switched on (indicator 11 lights up
green), the laser point or laser line can be rotated by 360° in
steps within the rotational plane, no matter if the measuring tool
is in horizontal or vertical position.
To rotate the rotational plane in clockwise direction, press but-
ton 10; to rotate anticlockwise, press button 9. Pressing and
holding the buttons increases the speed of the rotation head in
the desired direction.
Aligning the Rotational Plane in the Vertical Position
(RL25HV)
When the measuring tool is in the vertical position, it is possible
to rotate the laser point, laser line or rotational plane around the
Y-axis for easy sighting out or parallel alignment.
For this, press the button for single-axis slope operation 12; in-
dicator 11 flashes slowliy. Then, press button 10 to rotate the
rotational plane in clockwise direction, and button 9 to rotate in
anticlockwise direction. Pressing and holding the buttons in-
creases the speed of the rotation head in the desired direction.
Rotation is possible within a range of ±8 %.

Automatic Levelling

RL25H
After switching on, the measuring tool checks the horizontal
position and automatically compensates irregularities within
the self-levelling range of approx. 8 % (5°).
When the measuring tool is inclined by more than 8 % after
switching on or after a position change, levelling is no longer
possible. In this case, the rotor is stopped, the laser flashes, the
automatic levelling indicator 3 and the indicator for single-axis
slope operation 11 alternately flash green.
In this case, switch the measuring tool off, re-align it and switch
the measuring tool on again. Without repositioning, the laser is
automatically switched off after 2 min and the measuring tool
after 30 min.
When the measuring tool is levelled in, it continuously checks
the horizontal position. Automatic re-levelling takes place after
position changes. To avoid faulty measurements, the rotor
stops during the levelling process, the laser flashes and the
levelling indicator 3 rapidly flashes green.
