Horizontal Beam Out-of-Plane Tilt
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).
Vertical Beam Tilt
Position the instrument on the floor and project a vertical beam along a line x of about 6'
(1.9 m). Mark point a on the ceiling. Position the instrument on the other side of the line
and repeat marking point b on the ceiling. The distance d should be ≤5/32" (4 mm) for a
33' (10 m) ceiling or ≤3/32" (2 mm) for a 15' (4.6 m) ceiling.
