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 mode 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 0.75 mm

indication of the actual deviation of
the laser level from the ideal plumb
line.
If the measuring distance is 5m,
the maximum permissible deviation
is:
5 m x (+/- 0.3 mm/m) x 2 = +/ - 3 mm.
