4. Adjust the height of the tool (using the tripod or
by adding shims, if required) such that the center
of the horizontal line is projected exactly against
the previously marked point II on wall B. Ensure
the Laser is self-leveled after alignment.
5. Mark the center of horizontal line on wall A (point
III). Take care that point III is aligned as vertical
as possible above or below point I.
6. The distance d between marked points I and III on
wall A indicates the actual deviation (d) of the tool.

5. Move the laser level directly behind point II on the
other side of the door. Align the vertical laser line
so the center is directly aligned with points I and II.
6. Mark the center of the vertical line at the upper
edge of the door opening (point IV).
7. Measure the height of the door opening.
8. The distance between points III and IV on the
upper door opening is the vertical deviation (d)
of the tool.

A free measuring space of approximately 10m (33')
x 10m (33') on a firm surface between two walls or
structures A and B is required for the check.
It is also suggested to mount the Laser Level to a
commercially available Tripod for easy adjustment.
Securely mount the tool on one side of the room
and centered between walls A and B. Direct the
laser lines toward the other side of the room such
that the horizontal line appears on both walls A and
B. Allow the laser to Self-Level.
At a distance of 5m from the laser, mark the
centre of the horizontal line on Wall A (Point I). Do
the same on Wall B (Point II).
Move the Laser 10m toward the opposite wall
and rotate the laser 180°. Allow the laser to
Self-Level.
Mark the centre of the vertical laser line on the
floor in the middle of the door opening (point I), at
a distance of 2.5m (8') beyond the door opening
(point II), and at the upper edge of the door
opening (point III).
Securely mount the tool 2.5m from one side of
the door opening.
A door opening with approximately 2.5m of space on
each side of the opening is required for this check.
For the Measuring distance of 2 x 10m = 20m,
the maximum allowable deviation (d) is: 20m x
±3.18mm ÷ 10m = ±6.36mm
Thus, the difference d between points I and III
should not exceed 6.5mm (max.) at 20m.
