Roughly align the laser using the built-in vial, i.e. set the bubble roughly in the
centre of the vial. Turn the deflector prism's beam emission opening by hand in
the direction of the wall.
The LAPR-150 rotation laser has been designed for building site use and leaves our
factory perfectly calibrated. As with any precision instrument, however, its
calibration must be regularly checked. The unit should be checked before starting
any new tasks, particularly when the unit has been exposed to strong vibrations.
After an impact, the unit should be checked throughout its whole self-leveling
range.

If the difference between the control points is less than 2mm ( 1/8”) at 5m ( 26ft )
distance and 4mm ( 3/16” ) at 10m ( 39ft ) distance the permissible tolerance of
± 0.2 mm/m ( ± 1/4” over 100ft ) is being maintained.
Repeat steps 4 and 5 to obtain Points 3 and 4.
Mark the position of the visible laser dot on the wall (Point 2).
Mark the position of the visible laser dot on the wall - Measurement 1 (Point 1).
Because the diameter of the beam depends on the distance, you must always
only use the center of the dot!
Set up the rotation laser on a smooth, level surface or on a tripod 5m ( 26 ft )
or 10m ( 39ft ) from a wall with the front side facing the wall.
Turn the complete unit 90° without altering the height of the laser (i.e. the tripod
must not be altered) and turn the deflection prism in the direction of the wall
again in the area of measurement point 1.
