8. Checks

8.1 Checking the vertical (plumb) beam
1. Make a mark on the floor (a cross) in a high room (e.g.
in a stairwell or hallway with a height of 5–10 m).
2. Place the tool on a level surface (floor).
3. Switch on the vertical beam.
4. Position the tool with the lower beam on the center
of the cross.
5. Mark the position of the vertical beam on the ceil-
ing (attach a piece of paper to the ceiling).
6. Pivot the tool through 90°. The reference beam must
remain on the center of the cross.
7. Mark the position of the vertical beam on the ceil-
ing.
8. Repeat the procedure after pivoting the tool through
180° and 270°.
-NOTE-
The resulting 4 marks define a circle in which the inter-
section of the diagonals d1 (1 – 3) and d2 (2 – 4)
marks the exact center of the plumb point.

The result provided by this formula refers to the tool's
accuracy in mm at 10 m (formula (1)). This result should
be within the specification for the tool (3 mm at 10 m).

The tool is switched off.
●
The batteries are exhausted.
●
The batteries are inserted incorrectly.
●
The laser beam is switched on. The tool is in opera-
●
tion.
The batteries are almost exhausted.
●
The temperature of the tool is above 40 °C (104 °F)
●
or below –10 °C (14 °F) (no laser beam projected).
The batteries are almost exhausted.
●
The tool is in the closed position.
●
The pendulum is locked.
●
The tool cannot level itself automatically.

8.2 Checking the front beam and/or perpendicular
beam for height deviation
1. Place the tool on a smooth, horizontal surface approx.
20 cm from the wall (A) with the laser beam directed
toward the wall (A).
2. Mark the position of the center (1) of the laser beam
on the wall (A) with a cross.
3. Pivot the tool through 180° and mark the center of
the laser beam (2) on the opposite wall (B) with a
cross.
4. Place the tool on a smooth, horizontal surface approx.
20 cm from the wall (B) with the laser beam directed
toward the wall (B).
5. Mark the position of the center (3) 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 (4) on the opposite wall (A) with a
cross.
Calculation of accuracy
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 dif-
ferent sides of the mid point (see example), 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).
