The Precision Level Vials
Reading the Precision Level Vials
Secure the laser base to a metal surface by
turning the locking magnetic base ON. Once
the laser is in position, power it on and use the
adjustment knobs to bring the bubbles to the
center of both vials (see Figure 8).
When both the PITCH and ROLL vials are
reading level, the laser plane will be level to
earth to within .00016 in/ft (0.015 mm/m) for
the Precision Levels and .00006 in/ft (0.005
mm/m) for the Split-Prism Levels

Level Vials
Once the laser unit is in position on the base,
power it on and use the
coarse
alignment
micrometers to bring the bubbles to the
center of the level window.
When the bubbles are close to the center, use
the
fine
adjustment micrometers to align the
bubble halves to each other in the viewing
prism window (see Figure 9). When both the
PITCH and ROLL axis vials are reading
level, a level beam can be scanned at 360
degrees with a .0003 in. (0.0075 mm)
deviation per 10 ft. (3 m).
