When the measuring tool is in the vertical posi-
tion and set to automatic levelling, it is possible
to rotate the rotational plane around the X-axis by
pressing the upper 20 or lower 23 direction push-
button. Five seconds after last pressing on either
of the four direction pushbuttons, the rotation
plane is automatically levelled-in vertical again.
Line Operation
To switch to line operation, press the pushbutton
for line operation 19. Depending on the previous
operating mode, the measuring tool switches to
point operation or to the line operation with the
smallest aperture angle. Repeated pressing of
the pushbutton 19 switches the measuring tool
via the smallest aperture angle of 4° to the 30°,
60° and 180° aperture angles. At the same time,
the speed is increased with each step. When
pressing the pushbutton 19 again, the measuring
tool returns to point operation.
Changing the Aperture Angle: When the meas-
uring tool is in the horizontal position and set to
automatic levelling, it is possible to increase or
reduce the aperture angle by pressing the upper
20 or lower 23 direction pushbutton. The speed
remains unchanged.
Rotating the Aperture Angle: When the measur-
ing tool is in the horizontal position and set to
automatic levelling or inclined operation in a sin-
gle axis, it is possible to rotate the laser line or
the laser point by 360° in steps by pressing the
left 21 or right 24 direction pushbuttons. When
the measuring tool is in the vertical position
and set to automatic levelling, the rotation is ac-
tuated by pressing the upper 20 or lower 23 di-
rection pushbuttons.
Point Operation
Point operation can be switched on either by
pressing the pushbutton for rotational opera-
tion 22 or the pushbutton for line operation 19:
– When the measuring tool is set to rotational
operation and the pushbutton for line opera-
tion 19 is pressed, then the measuring tool
1 609 929 L80 | (26.7.07)
starts with point operation. Exception: The
measuring tool was already in point opera-
tion by having pressed the pushbutton for ro-
tational operation 22. In this case, line oper-
ation immediately starts with the smallest
aperture angle upon pressing the pushbut-
ton for line operation.
– When the measuring tool is set to line opera-
tion and the pushbutton for rotational opera-
tion 22 is pressed, then the measuring tool
also starts with point operation. Exception:
The measuring tool was already in point op-
eration by having pressed the pushbutton for
line operation 19. In this case, rotational op-
eration immediately starts with the highest
rotational speed upon pressing the pushbut-
ton for rotational operation.
Working with Automatic Levelling
Overview
After switching on, the measuring tool automat-
ically detects the horizontal or vertical position.
To change between the horizontal and vertical
position, switch the measuring tool off, reposi-
tion it and switch on again.
After switching on, the measuring tool checks
the horizontal and vertical position and auto-
matically levels out any unevenness within the
self-levelling range of approx. 8 %
( ± 0.8 m/10 m).
When the measuring tool, after switching it on
or after a position change, is out-of-level by
more than 8 %, levelling in is no longer possible.
As long as the out-of-level safety was not acti-
vated (see "Out-of-level Safety"), a slow-se-
quence warning signal sounds, the rotor is
stopped, the laser beam and the "auto" 26
as well as the "man" 25 indicators flash once
per second. In this case, switch the measuring
tool off, realign it and then switch the measuring
tool on again.
