Repeat this until both positions read zero and no further adjustments are necessary.
Note: Place the target in exactly the same place each time you move from near to far or from far to near.
Marking the footprint is usually the best way to ensure that you are back in the same spot each time you move
the target. Also, make it a habit to clean the bottom of the base and the surface with your hand before placing
the target on the footprint.
Always ADJUST the TARGET to zero on the near point. Always AIM the LASER to zero on the
far point.
When both near and far points produce zero readings, the laser beam is parallel to these two points.
Any number of points in between these two points may now be checked to see if they are in that same
line. If the readings are + (plus) numbers, the points are higher than the line drawn from the near
point to the far point. If the numbers are - (minus) numbers, the points are lower than the line drawn
from the near point to the far point.
Close versus Remote Buck-In
There are two procedures for bucking
in the laser, the close and the remote
buck-in. The procedure used depends
on the relationship of two distances:
the distance between the laser unit and
the first target, and the distance
between the first and second targets.
The close buck-in is easier; the remote
buck-in is useful in situations where the
close method would be nearly
impossible.
Figure 51 illustrates the general rule for
determining the buck-in method to use.
L1 represents the distance from the
laser to the first target. L2 represents
the distance between the two targets. If
L1 is less than one tenth of L2, the
close buck-in procedure is used. If L1
is greater than one tenth of L2, the
remote buck-in procedure should be
used. When in doubt, or if the close
procedure is not producing good
results, use the remote procedure.
