1. Hang an approximately 2 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
flat surface in front of the wall at a
distance of approximately 2,5 m.
4. Switch ON the self-leveling mode, and
press the button to project the vertical
beam towards the plumb line.
5. Turn the 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 1.3 mm
