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.

7.3.3 Checking the perpendicular beams for

height deviation

Repeat the procedure and calculate the accuracy of
each of the two perpendicular beams as described at
7.3.2 and 7.3.2.1.

7.3.4 Checking the angle between the point

of intersection of the laser lines and the
perpendicular beams

NOTE

In the following procedure, the terms “left” and “right”
refer to the following perspective: tool seen from
behind, looking toward the point of intersection of the
laser lines.

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 on all laser beams.
3. Fix a target plate at a distance of at least 10 m

from the tool so that the point of intersection of
the laser lines strikes 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 vertical line on the second target plate must
run exactly through the middle of the vertical laser
line.

5. Fix the second target plate at a distance of 5 m

from the reference point (marked at step 4) so
that the vertical line on the second target plate
lies exactly in the middle of the vertical laser line.

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) runs exactly through the
middle of the vertical laser line.

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 mid point (d1)
of the right 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 right perpendicular beam must lie exactly
on the vertical line on the second target plate
(from step 5).

9. Mark the mid point (d2) of the right perpendicular

beam on the second target plate (from step 5).

10. Mark the mid point (d3) of the point of intersection

of the laser lines on the target plate or paper (from
step 7).

NOTE

The horizontal distance between d1 and

d3 must be no greater than 3 mm at a working
distance of 5 m.

11. Pivot the tool clockwise through 180° (as seen

from above). The lower plumb beam must remain
in the center of the reference cross and the center
of the right perpendicular beam must lie exactly
on the vertical line on the first target plate (from
step 3).
