10. For calculation of deviation in accordance with the
above method, the maximum permissible deviation
is as follows:
11. The maximum permissible deviation in millimeters
must be less than 0.3 mm/m multiplied by twice the
distance in meters between the two walls.
d = twice the measured deviation in millimeters / ¹⁄₁₀
inch
D = distance between the two walls in meters/feet
7.2.2 Checking the accuracy of the horizontal
line 4 5
1. Place the tool at the edge of a room with a length of
at least 10 m.
NOTE The floor surface must be even and level.
2. Switch all laser beams on and make sure that the
pendulum lock is disengaged.
3. Make a mark at a distance of at least 10 m from the
tool, so that the point of intersection of the laser lines
lies in the center of the mark (d0) and the vertical
line of the mark runs exactly through the middle of
the vertical laser line.
4. Pivot the tool clockwise through 45° (as seen from
above).
5. Then mark the point (d1) on the mark where the
horizontal laser line strikes the vertical line on the
mark.
6. Pivot the tool counterclockwise through 90°.
7. Then mark the point (d2) on the mark where the
horizontal laser line strikes the vertical line on the
mark.
8. Measure the following vertical distances: d0-d1, d0-
d2 and d1-d2.
9. For d0-d1, d0-d2 and d1-d2, the following applies:
10. The greatest measured vertical distance must be no
more than 5 mm at a working distance of 10 m.
dmax-dmin = distance between the highest mark
and the lowest mark in millimeters / ¹⁄₁₀ inch
D = distance between the tool and the mark in
meters / feet
7.2.3 Checking the accuracy of the vertical
line 6 7
To perform this check you require a door opening or
similar object with a clear height of at least 2 meters. In
addition to this, you require free space of at least 2.5
meters on each side.
1. Switch the tool on and make sure that the pendulum
lock is disengaged.
2. Stand the tool on the floor at a distance of 2.5 m
from the door opening and align the tool so that the
vertical line is positioned in the middle of the door
opening.
3. Mark the middle of the vertical line on the floor (1)
and at the top edge of the door opening (2) and also
on the floor at a distance of 2.5 meters behind the
door opening (3).
4. Position the tool immediately behind point (3) on
the floor and align the laser beam so that it passes
through points (3) and (1).
5. The deviation between the laser line and point (2)
can be read directly at the top edge of the door
opening. This value corresponds to the deviation at
twice the height.
6. Measure the height of the door opening.
7. The maximum permissible deviation is 3 mm per 10
m height.
8. For calculation of deviation in accordance with the
above method, the maximum permissible deviation
is as follows:
9. The maximum permissible deviation in millimeters
must be less than 0.3 mm/m multiplied by twice the
height in meters.
d = twice the measured deviation in millimeters / ¹⁄₁₀
inch
H = height of the door opening in meters
7.2.4 Procedure in the event of deviations
In the event of finding deviations, please return the tool to
a Hilti Measuring Systems Service Center for servicing.
