1. Turn the tool to
ON and to
Horizontal Leveling Accuracy
It is also suggested to mount the Laser Level to a
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.

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.

A free measuring space of approximately
10m x 10m on a firm surface between two walls or
structures A and B is required for the check.
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.

5. Move the laser level directly behind point II on the
other side of the door. Align the vertical laser line
so the centre is directly aligned with points I and II.
6. Mark the centre 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.
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 beyond the door opening
(point II), and at the upper edge of the door
opening (point III).
A door opening with approximately 2.5m of space on
each side of the opening is required for this check.
Securely mount the tool 2.5m from one side of
the door opening.
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
6.36mm (max.) at 20m.
