centers of each set of marks. If there is a differ-

This calibration method magnifies any error by a
factor of two. Therefore divide any difference by
two to find the true error. Your PLS480 should have
an error of no greater than 1/8in. within 60ft.

CHECKING THE PLS480 ON THE JOB SITE
USING PYTHAGORAS 3-4-5 TRIANGLE:
Set up over the center of PEG (A) using the
plumb down laser dot.
Using one of the 90 degree beams put PEG (B)
in the ground at an exact distance of 15M/45 FT
from PEG (A).
Using the other 90 degree beam, put PEG (C)
in the ground at an exact distance of 20m/60 FT
from PEG (A).
Now measure with a tape diagonally from
PEG (B) to PEG (C). The distance should
be 25M/75FT.
