There are several easy methods to check the calibration and accuracy of the PLS
5
and PLS
3
.
We recommend that you check this periodically.
METHOD 1 (PLS
5
only) Quick Check of Performance Accuracy. Place the PLS
5
on a stable
surface 25’-0” or more from a suitable wall or target. See Fig. 8. Point the #1 forward beam at
the wall or target and carefully mark the center of elevation. Swivel the PLS
5
90˚ on its center
until the #5 right beam is over the first mark. Check to see if there is any difference in elevation
from the center of #1 forward beam and the center of #5 right beam. Repeat to check #4 beam.
At 50’-0” the difference should not be greater than 1/8.” At 25’-0” the difference should not be
greater than 1/16.”
