10. Adjust the yaw adjustment on
the laser base so that LP#2 is
tilted until both Target #2 and #3
show the same readings. LP#2 is
now parallel to the offset
centerline.
Note: The readings do not have to
be zero, but just the same number
and same sign.
11. To measure one of the rolls for
parallelism, place Target #1
horizontally on the roll closest to
the laser. Adjust the post so the
laser plane is near the center of
the target. Move the magnetic
base up/down the roll until the
bubble is level. Zero Target #1
in Read15.
12.
Move Target #1 to the far end of
the roll. The resulting value is a
measure of the parallelism of
this roll relative to the reference
roll. In this case, a plus ( +)
reading means the far end of the
roll is pointing to the right by
.025 in. To align it, adjust the
roll until the readout shows
zero, which means the roll is
aligned and parallel to the
reference roll.
