Pressing the line operation button 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.
Rotating the Laser Line/Laser Dot or the Rotational Plane (see figure A)
When the measuring tool is in the
horizontal position
, the laser line (in line operation) or the laser dot (in point operation) can be positioned within the rotational plane of the laser. Rotation is possible by 360°.
For this, manually turn the rotation head
10
to the desired position or use the remote control: Press button
28
to rotate in clockwise direction, and button
29
on the remote control to rotate in anticlockwise direction. In rotational operation, pressing the buttons has no effect.
When the measuring tool is in the
vertical position
, it is possible to rotate the laser point, laser line or rotational plane around the vertical axis. Rotating is possible only within the self-levelling range (5° leftwards or rightwards) and only with the remote control.
Press button
28
on the remote control to rotate in clockwise direction, and button
29
on the remote control to rotate in anticlockwise direction.
Automatic Levelling of the Rotational Laser Level
Overview
After switching on, the measuring tool automatically detects the horizontal or vertical position. To change between the horizontal and vertical position, switch the measuring tool off, reposition it and switch on again.
After switching on, the measuring tool checks the horizontal and vertical position and automatically levels out any unevenness 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 in is no longer possible. In this case, the rotor is stopped, the laser flashes and levelling indicator
3
continuously lights up red. Reposition the measuring tool and wait for it to re-level. Without repositioning, the laser is automatically switched off after
2 minutes and the measuring tool after 2 hours.
When the measuring tool is levelled in, it continuously checks the horizontal and vertical 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
flashes green.
Shock-warning Function
The measuring tool has a shock-warning function; after position changes or shock to the measuring tool, or in case of ground vibrations, it keeps the measuring tool from levelling in at changed heights, and thus prevents vertical errors.
– To
switch on
the shock-warning function, press the shockwarning button
2
. The shock-warning indicator
1
continuously lights up green, and the shock-warning function is activated after 30 seconds.
