Horizontal Beam - Pitch Direction
E
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.
Place the laser against the end of the wall on a

Vertical Beam (DW089)
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 fl oor 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.
