Vertical Beam Accuracy
(See figure
L
)
• L
1
Measure the height of a reference point to get distance
D
1
. Place laser tool as shown with laser ON. Aim vertical
beam towards reference point. Mark points P
1
, P
2
, and
P
3
as shown.
•
L
2
Move laser tool to opposite side of reference point and
align the same vertical beam with P
2
and P
3
.
• L
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:

≤ Maximum
Example:
• D
1
= 3 m, D
2
= 1,0 mm
• 0,8
mm
m
x 3 m = 2,4 mm
(maximum offset distance)
• 1,0 mm ≤ 2,4 mm
(TRUE, tool is within calibration)
Horizontal Beam Accuracy
(Without Vertical Beam) - (See figure
K
)
• K
1
Place laser tool as shown with laser ON. Roughly aim
the laser tool towards the first corner or a set reference
point. Measure out half of the distance D
1
and mark point
P
1
.
• K
2
Rotate and roughly aim laser tool towards point P
1
.
Mark point P
2
so that it is vertically in line with point P
1
.
•
K
3
Rotate laser tool and roughly aim 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
.
• K
4
Measure the vertical distance D
2
between the highest
and lowest point.
• Follow same calculations / example when accuracy was
checked with vertical beam.
