CHECKING LASER BEAMS FOR LEVEL ACCURACY
Horizontal Beam Left/Right Tilt (FIG. 1)
Secure instrument via its mounting bracket at a distance x from a vertical wall
structure 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. Rotate the instrument
to the right and repeat
marking the vertical location
of the left side of the beam.
At ~33' (10 m) the vertical
distance d between the
left-side and right-side
markings should be ≤ 5/32" (4 mm).
For example, if x is set to 15' (4.6 m),
the vertical distance d should be ≤3/32" (2 mm).
Horizontal Beam Out-of-Plane Tilt (FIG. 2)
Position the instrument parallel to a wall and project a beam along the wall, from
left to right as shown. Mark two locations (a, b) along the beam separated by distance x.
Position the laser at the other side of the wall and project the beam back through mark
b, from right to left as shown, and mark position c. If x is 30' (9.1 m), then the vertical
distance d should be ≤ 5/32" (4 mm). For example, if x is set to 15' (4.6 m), then the
vertical distance d should be ≤ 3/32" (2 mm).
