Vertical Beam Accuracy
(See fi gure
M
)
•
M
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.
•
M
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
.
•
M
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
1
= 2 m, D
2
= 0,3 mm
• 0,4
mm
m
x 2 m = 0,8 mm (maximum offset distance)
• 0,3 mm ≤ 0,8 mm (TRUE, tool is within calibration)
Up and Down Beam Accuracy
(SCL-D only / See fi gure
N
)
•
N
1
Place laser unit as shown with laser ON. Measure
distances D
1
and D
2
. Mark points P
1
and P
2
.
•
N
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
.
•
N
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:
= (D

≤ Maximum
Example:
• D
1
= 3 m, D
2
= 1 m, D
3
= 1,5 m
• (3 m x 0,4
mm
m
) + (1 m x 0,8

m
) = 2,0 mm
(maximum offset distance)
• 1,5 mm ≤ 2,0 mm (TRUE, tool is within calibration)
