Horizontal Beam Accuracy
Checking the horizontal pitch calibration of the
laser requires a single wall at least 30' (9m) 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 Accuracy
Checking the vertical (plumb) calibration of the
laser can be most accurately done when there is
a substantial amount of vertical height available,
ideally 30' (9m), 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.
Place the laser at least 3.28 ft (1.0m) from a door
