Place laser tool as shown with laser ON. Mark point
P

at cross.
•
G

at cross.
•
G

at cross.
•

5
Measure the vertical distance between P
1
and P
3
to get
D
3
and the vertical distance between P
2
and P
4
to get D
4
.
• Calculate the maximum offset distance and compare to the
difference of D
3
and D
4
as shown in the equation.
• If the sum is not less than or equal to the calculated
maximum offset distance the tool must be returned to
your Stanley Distributor for calibration.

Example:
• D

x (10 m - (2 x 0,5 m) = 3,6 mm
(maximum offset distance)
• (1,0 mm) - (- 1,5 mm) = 2,5 mm
• 2,5 mm ≤ 3,6 mm
(TRUE, tool is within calibration)

• Follow same calculations / example as when accuracy was
checked with vertical beam.
Horizontal Beam Accuracy
(See figure
J
)
•
J
1
Place laser tool as shown with laser ON. Aim vertical
beam towards the first corner or a set reference point.
Measure out half of the distance D
1
and mark point P
1
.
•
J
2
Rotate laser tool and align front vertical laser beam
with point P
1
. Mark point P
2
where the horizontal and
vertical laser beams cross.
•
J
3
Rotate laser tool and aim vertical beam towards the
second corner or set reference point. Mark point P
3
so that
it is vertically in line with points P
1
and P
2
.
•
J
4
Measure the vertical distance D
2
between the highest
and lowest point.
• Calculate the maximum offset distance and compare to D2 .
• 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.
