Vertical Beam Accuracy (See figure
J
)
•
J
1
Measure the height of a door jamb or reference point
to get distance D
1
. Place laser tool as shown with laser
ON. Aim vertical beam towards door jamb or reference
point. Mark points P
1
, P
2
, and P
3
as shown.
•
J
2
Move laser tool to opposite side of door jamb or
reference point and align the same vertical beam with
P
2
and P
3
.
•
J
3
Measure the horizontal distances between P
1
and the
vertical beam from the 2nd location.
• Calculate the maximum offset distance and compare
to D
2
.
• If D
2
is not less than or equal to the calculated
maximum offset distance the tool must be returned
to your Stanley Distributor for calibration.
Maximum Offset Distance:

Example:
• D

= 2 m, D
2
= 0,5 mm
• 0,4
mm
m
x 2 m = 0,8 mm
(maximum offset distance)
• 0,5 mm ≤ 0,8 mm
(TRUE, tool is within calibration)
Up and Down Beam Accuracy ( See figure
K
)
•
K
1
Place laser unit as shown with laser ON. Measure
distances D
1
and D
2
. Mark points P
1
and P
2
.
•
K
2
Rotate laser unit 180° keeping same distances for
D
1
and D
2
. Align downward laser beam with point P
2
.
Mark point P
3
.
•
K
3
Measure distance D
3
between points P
3
and P
1
.
• Calculate the maximum offset distance and compare
to D
3
.
• If D
3
is not less than or equal to the calculated
maximum offset distance the tool must be returned
to your Stanley Distributor for calibration.
Maximum Offset Distance:

Example:
• D

3
= 1,5 m
• (3 m x 0,4

m
) + (1 m x 0,8
