Working without a tripod: Determine the height difference
between the laser beam and the height at the reference
point using the laser target plate (53). Project or check the
height difference measured at the target location.
Parallel Alignment of Upwards Plumb Point/Projecting
Right Angles (see figure G)
When right angles are to be projected or partition walls are
to be aligned, the upwards plumb point (10) must be aligned
in parallel, meaning at the same distance to a reference line
(e.g. a wall).
For this, set up the measuring tool in the vertical position
and position it in such a manner that the upwards plumb
point runs approximately parallel to the reference line.
For the exact positioning, measure the clearance between
the upwards plumb point and reference line directly on the
measuring tool using the laser target plate (53). Measure the
clearance between the upwards plumb point and reference
line again as far away as possible from the measuring tool.
Align the upwards plumb point in such a manner that it has
the same clearance to the reference line as when measured
directly at the measuring tool.
The right angle to the upwards plumb point (10) is indicated
by the variable laser beam (8).
Indicating a perpendicular/vertical plane (see figure G)
To indicate a perpendicular or a vertical plane, set up the
measuring tool in the vertical position. When the vertical
plane is supposed to run at a right angle to a reference line
(e.g. a wall), align the upwards plumb point (10) with this
reference line.
The perpendicular plane is indicated by the variable laser
beam (8).
Aligning a Perpendicular/Vertical plane (see figure H)
To align the vertical laser line or the rotational plane against
a reference point on a wall, set up the measuring tool in the
vertical position, and roughly align the laser line or the rota-
tional plane with the reference point. For precise alignment
with the reference point, turn the rotational plate around the
X-axis (see "Turning the rotational plane when in the vertical
position", page 41).

Working without the laser receiver

Under favourable light conditions (dark environment) and
for short distances, it is possible to work without the laser
receiver. For improved visibility of the laser beam, either se-
lect line operation or point operation and rotate the laser
beam to the target location.
Working with the laser receiver (see figure E)
In unfavourable lighting conditions (bright environment, dir-
ect sunlight) and for larger distances, use the laser receiver
1 609 92A 55C | (05.11.2019)
to improve detection of the laser beam (42). When working
with the laser receiver, select rotational operation with the
highest rotational speed.
Working outdoors (see figure E)
The laser receiver (42) should always be used when working
outdoors.
When working on unstable ground, mount the measuring
tool on the tripod (44). Always work with the shock-warning
function activated in order to avoid faulty measurements in
case of ground movements or shocks to the measuring tool.
Setting up formwork (see figure I)
Mount the measuring tool in the horizontal position on a tri-
pod (44) and set up the tripod outside the formwork area.
Select rotational operation.
Secure the laser receiver (42) to a measuring rod (43) with
the holder. Position the measuring rod on a reference point
for the formwork.
Align the height of the laser receiver on the measuring rod so
that the variable laser beam (8) of the measuring tool is in-
dicated as "centred" (see operating instructions for the laser
receiver).
Then position the measuring rod with the laser receiver, one
after the other, at different test locations on the formwork.
Make sure that the laser receiver remains in the same posi-
tion on the measuring rod.
Correct the height of the formwork until the laser beam is in-
dicated as "centred" at all test locations.
Checking slopes (see figure J)
Mount the measuring tool in the horizontal position on a tri-
pod (44). Select rotational operation.
Set up the tripod with the measuring tool so that the X-axis is
aligned with the slope that is to be checked.
Position the target slope as the slope for the X-axis (see
"Slope operation in the horizontal position", page 43).
Secure the laser receiver (42) to a measuring rod (43) with
the holder. Place the measuring rod at the base of the slope
surface.
Align the height of the laser receiver on the measuring rod so
that the variable laser beam (8) of the measuring tool is in-
dicated as "centred" (see operating instructions for the laser
receiver).
Then position the measuring rod with the laser receiver, one
after the other, at different test locations on the slope sur-
face. Make sure that the laser receiver remains in the same
position on the measuring rod.
If the slope of the plane is correct, the laser beam will be in-
dicated as "centred" at all test locations.
