Aligning Direction of Grade
When using the laser with a percent of grade entered,
the laser must be properly aligned so the slope of the
laser beam is parallel to the desired direction of grade.
The sighting collimator on top of the instrument is cali-
brated to the grade axis of the laser beam. Follow the
steps below to align the laser to the desired direction of
grade:
1
Establish a target line parallel to desired direction of
grade.
2
Set up the laser over this line (drop a plumb bob from
the tripod mounting screw).
3
Rough align the instrument to the direction of grade.
Make sure it is properly oriented for the grade to be
entered, positive or negative. (See page 18)
4
Place a rod or other target down range on the target line.
5
While sighting through
the collimator, adjust the
instrument until the sight
is aligned with the tar-
get. (see right)
