CHECKING PLUMB ACCURACY
This procedure requires a room
with approximately 5 m distance
between fl oor and ceiling.
1. Open the folding legs of the
laser and place it on the  oor.
2. Turn on the self-leveling mode
and press the push button to
project the vertical cross
beams on the ceiling and the
plumb down on the
 oor.
3. Mark the centre of the upper
cross beam on the ceiling as
point a1 (see the illustration).
4. Mark the centre of the plumb
dot on the fl oor as point b.
5. Rotate the laser level 180°.
Position it so that the centre of
the plumb dot is on the point b,
which has already been
marked, and allow it to level.
6. Mark the centre of the upper
cross beam on the ceiling as
point a2.
7. The distance between points
a1 and a2 marked on the
ceiling is an indication of the
actual deviation of the laser
level from the ideal plumb line.
If the measuring distance is
5 m, the maximum permissible
deviation is:
5 m x (+/- 0.6 mm/m) x 2 = +/- 6 mm.
8. The distance between a1 and
a2 should not be more than 6
mm.
