Vertical Beam
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.
