Points
Check of Plumb Accuracy. This
requires signicant vertical height
(minimum 10’-0”) and the ability
to mark at that height. Place the
unit with the down beam exactly
centered on both axes over a cross
mark. At the surface above, mark
both axes of up beam. Rotate the laser 180˚ and
place the down beam exactly centered on the original
mark. The up beam should be exactly over the
original mark.
If there is a difference between marks the error of the
plumb beam is one half that difference.

We recommend that you check your PLS4 periodically
in order to assure its accuracy.
TO CHECK LEVEL:
Choose two interior walls approximately 15’-0” apart (see
Fig. 1). You can use 2 x 4s for targets.
Turn on the PLS4 to setting #1 (level). With the PLS4 six
inches away from and facing target #1, carefully mark the
center of the line. Label this mark A1. Swivel the laser
180º and mark the center of the line on target #2. Label
this mark B1.
Move the PLS4 six inches away from and
facing target #2. Carefully mark the center of the line.
Label this mark B2. Swivel the laser 180º and mark the
center of the line on target #1. Label this mark A2.
You now have two centers of elevation at each
target. Carefully measure the distance between centers
of each set of marks. If there is a difference, subtract one
measurement from the other. This calibration method mag-
nies any error by a factor of two. Therefore divide any
difference by two to nd the true error. Your PLS4 should
have an error of no greater than 1/8 in. within 30ft.
Lines
Choose a door jamb with 8’-0”
clear on each side of the door.
Turn on your PLS4 laser to set-
ting #2 (plumb). With your laser
at point A, make two marks on
the oor: the rst at 8’-0” from
point A centered on door
header above (mark this
point B), the second 16’-0”
from point A (mark this
point C). Without moving the laser, make
a third mark on the door header (mark this point D).
Move the laser to point C, exactly
align the beam with point B, and no-
tice where the beam falls at point D.
If it is within a “light” 1/16” of point
D, the laser is in calibration.
