Horizontal Beam - Pitch Direction
Checking the horizontal pitch calibration of the laser requires
a single wall at least 9m (30') long. It is important to conduct
a calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.

Vertical Beam - Plumb
Checking the vertical (plumb) calibration of the laser can be
most accurately done when there is a substantial amount of
vertical height available, ideally 9m (30'), with one person on
the floor positioning the laser and another person near a ceiling
to mark the position of the beam. It is important to conduct
a calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.
1.
Place the laser on a smooth, flat, stable surface that is
level in both directions (Figure
