3. Pivot the tool through 180° and mark the center
of the laser beam (4) on the opposite wall (B)
with a cross.
4. Place the tool on an even, level surface approx.
20 cm from the wall (B) with the laser beam
directed toward the wall (B).
5. Mark the center of the laser beam on the wall (B)
with a cross.
6. Pivot the tool through 180° and mark the center
of the laser beam on the opposite wall (A) with a
cross.
7.3.2.1 Calculation of accuracy
6mm – 4mm
=
10 x 2
1. Measure the distances d1 between 1 and 4 and
d2 between 2 and 3.
2. Mark the mid points of d1 and d2.
If the reference points 1 and 3 are located on
different sides of the mid point, then subtract d2
from d1.
If the reference points 1 and 3 are located on the
same side of the mid point, then add d1 and d2
together.
3. Divide the result by twice the length of the room
(room length x 2).
The maximum permissible error is 3 mm at 10
m.
Example d1 = 6 mm/ d2 = 4 mm/ room length
(D) = 10 m
Points 1 and 3 are on different sides of the exact
horizontal.
7.3.3 Checking the angle between the
forward beam and the perpendicular
beam 9 10 11 12 13
1. Place the tool on a smooth, horizontal surface at
the edge of a room with a length of at least 10 m
and width of at least 5 m (or with the same 2:1
size ratio).
NOTE The floor surface must be smooth and
level.

2. Switch the tool on.
3. Fix a target plate at a distance of at least 10 m
from the tool so that the forward beam strikes
exactly the center of the target plate.
4. Using a second target plate, mark a reference
cross on the floor at a distance of 5 m (measure
the distance) from the first target plate.
The beam must strike the second target plate
exactly in the center (cross-hairs).
5. Fix the second target plate at a distance of 5 m
from the reference cross (marked at step 4) so
that the vertical line on the second target plate
lies exactly in the center of the front laser beam.
6. Now position the tool with the lower plumb beam
exactly on the center of the reference cross (from
step 4) so that the vertical line on the first target
plate (from step 3) lies exactly in the center of
the front beam.
7. Fix another target plate or a piece of stout paper
at a distance of 5 m from the perpendicular
beam, half-way, in the middle. Mark the center
point (d1) of the perpendicular beam.
8. Pivot the tool clockwise through 90° (as seen
from above). The lower plumb beam must remain
in the center of the reference cross and the center
of the perpendicular beam must lie exactly on
the vertical line on the second target plate (from
step 5).
9. Mark the center point (d2) of the front beam on
the target plate or paper (from step 7).
NOTE The horizontal distance between d1 and
d2 must be no greater than 3 mm at a working
distance of 5 m.
7.3.4 Calculation of accuracy (g) at a working
distance other than 5 m
g=(3 mm x working distance (m))/5 m.
In this case, the horizontal distance between d1 and
d2 must not exceed the value (g) at the defined
working distance (m).
