The measuring tool cannot stand level on an
uneven, soiled levelling plate surface, which could lead
to faulty measuring results.
Using the levelling plate you can position the measur-
ing tool flat on an uneven or unstable floor.
The levelling plate can also be used as a wall bracket
for the measuring tool. Fix the levelling plate (securing it
against slipping) on a wall or an inclined surface using e.g.
standard screws. Use a level to fix the levelling plate flat
on the surface.
Position the measuring tool with the magnets on
the underside on the levelling plate . The line grid on
the upper side of the levelling plate facilitates the precise
positioning of the measuring tool. In order to mark 90° or
45° angles, position the levelling plate at a reference edge
or a projection on a wall and position the measuring tool
as illustrated on the upper side of the levelling plate.
The laser target plate or the ceiling measurement plate
improves the visibility of the laser beam under unfa-
vourable conditions and at longer distances.
The reflective part of the laser target plate improves the
visibility of the laser line. Thanks to the transparent part,
the laser line is also visible from the back side of the laser
target plate.
The ceiling measurement plate (accessory) can also
be used for marking the laser lines. Like the laser target
plate, it has a reflective and a transparent part.
The laser viewing glasses filter out the ambient light. This
makes the red light of the laser appear brighter for the
eyes.
The laser viewing glasses are used for improved
visualisation of the laser beam, but they do not protect
against laser radiation.

The laser viewing glasses do not afford
complete UVprotection and reduce colour perception.
Position the measuring tool in one corner of the room and
position it so that the 0° laser line runs parallel to the ref-
erence line (e.g. wall). Measure the distance between the
laser line and the reference line directly at the measuring
tool and at the longest possible distance from the measur-
ing tool. Align the measuring tool so that both distances
are identical.
Then measure at at least two different points the distanc-
es between the 90° laser line and the wall. If the distances
to the 90° laser line are identical, the walls are at the right
angle.
Position the measuring tool in one corner so that the 0° la-
ser line runs parallel to one wall. Lay the first square tile at
the crossing point of the 0° and the 90° laser lines.
Position the measuring tool so that the 45° laser line
marks the diagonal tile joint.
Firstly determine the height at which the first tile row be-
gins. Fix the measuring tool with the levelling plate ver-
tically on the wall so that the 90° laser line marks the low-
er edge of the first tile row.
Position the measuring tool on the levelling plate at the
edge so that a lateral cut-out of the levelling plate is di-
rectly at the edge. The 0° laser line should run parallel to
one edge. The 90° laser line now marks the lower tile row.
Store and transport the measuring tool only in the sup-
plied protective pouch.
Keep the measuring tool clean at all times.
