VERIFYING ACCURACY OF LASER LINES
HORIZONTAL BEAM LEFT/RIGHT TILT
Position the instrument on the floor x distance from front of the device to
the vertical wall as shown. Rotate the instrument on the bracket to the left
so that the right side of the beam is projected on the wall directly across
from the instrument, mark the vertical location on the wall (a). Rotate the
instrument to the right and repeat marking the vertical location of the left
side of the beam (b). The maximum distance (delta) between a and b
is shown in the table below.
