CHECKING ACCURACY – HORIZONTAL BEAM, PITCH DIRECTION (FIG. 6)
Checking the horizontal pitch calibration of the laser requires a single
wall at least 9 m (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.
