CHECKING THE LEVEL ACCURACY OF THE VERTICAL
BEAM
1. Hang an approximately 4 m plumb
line on a wall.
2. After the plumb line has settled, mark
point a1 on the wall, behind the
plumb line, near the plumb cone.
3. Set up the cross laser on a tripod or
on a fl at surface in front of the wall at
a distance of approximately 2 m.
4. Switch ON the self-leveling mode,
and press the button to project the
vertical beam towards the plumb line.
5. Turn the cross laser so that the
vertical beam will merge with the
plumb line below the hanging point.
6. Mark point a2 on the wall, in the
middle of the vertical beam at the
same height as a1.
7. The distance between a1 and a2,
should be no more than 1 mm.

CHECKING 90º ACCURACY BETWEEN
THE 2 VERTICAL BEAMS
This procedure
requires a room of
at least 5x5 meters
with 4 walls.
1. Set up the cross
laser on a table
or on the fl oor in
the middle of the
room.
2. Switch ON the
self-leveling
mode, and press
the V/H button 4
times to project
a1
the forward and
the side vertical
beams
3. Mark the center
of the forward
vertical beam at
2 locations. point
a1 on the table
near the cross
laser, and point
a2 on wall A.
4. Mark the center
of the side
vertical beam at
2 locations. point
b1 on the table
near the cross
a2
laser, and point
a1
b2 on wall B.
