Working with the Laser Target Plate

The laser target plate (51) improves visibility of the laser
beam in unfavourable conditions and at greater distances.
The reflective surface of the laser target plate (51) improves
visibility of the laser line. The transparent surface enables
the laser line to be seen from behind the laser target plate.

Working with the Tripod (Accessory)

A tripod offers a stable, height-adjustable support surface
for measuring. For horizontal operation, place the measuring
tool with the 5/8" tripod mount (18) on the thread of the
tripod (43). Tighten the measuring tool using the locking
screw of the tripod.
For vertical operation, use the 5/8" tripod mount (20).
On a tripod featuring a measuring scale on its extender, you
can set the height deviation straight away.
Roughly align the tripod before switching on the measuring
tool.

Laser Goggles (Accessory)

The laser goggles filter out ambient light. This makes the
light of the laser appear brighter to the eye.
Do not use the laser goggles (accessory) as protective
u
goggles. The laser goggles make the laser beam easier to
see; they do not protect you against laser radiation.
Do not use the laser goggles (accessory) as
u
sunglasses or while driving. The laser goggles do not
provide full UV protection and impair your ability to see
colours.
Working with a wall mount and alignment unit
(see figure D)
The measuring tool can be secured to the wall using the wall
mount with the alignment unit (44). Using the wall mount is
recommended, e.g. when working above the maximum ex-
tension height of tripods, or when working on unstable sur-
faces without a tripod.
Fasten the wall mount (44) to a wall using screws through
the fixing holes (45). Fit the wall mount as vertical as pos-
sible and ensure it is mounted in a stable way.
Screw the 5/8" wall mount screw (48) into the horizontal tri-
pod mount (18), depending on the requirements of the task,
or the vertical tripod mount (20) on the measuring tool.
Using the alignment unit allows the measuring tool to be
moved in a range of approx. 13 cm with respect to height.
Press the button (46) and move the alignment unit to
roughly the required height. It is possible to align the laser
beam precisely to a reference height using the fine adjust-
ment screw (47).
Working with the measuring rod (accessory)
(see figure E)
To check levels or apply slopes, it is recommended to use
the measuring rod (42) together with the laser receiver.
A relative measuring scale is incorporated at the top of the
measuring rod (42). You can preselect its zero at the bottom
on the extender. This enables you to read deviations from
the target height straight away.

Example applications

Projecting/checking heights (see figure F)
Position the measuring tool in the horizontal position on a
firm support or mount it on a tripod (43) (accessory).
Working with a tripod: Set the laser beam at the required
height. Project or check the height at the target location.
Working without a tripod: Determine the height difference
between the laser beam and the height at the reference
point using the laser target plate (51). 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 (51). 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 43).

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
