Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out the ambi-
ent light. This makes the red light of the laser
appear brighter for the eyes.
f
Do not use the laser viewing glasses as
safety goggles. The laser viewing glasses
are used for improved visualisation of the
laser beam, but they do not protect
against laser radiation.
f Do not use the laser viewing glasses as
sun glasses or in traffic. The laser viewing
glasses do not afford complete UV protec-
tion and reduce colour perception.
Work Examples
Checking right angles (see figure A)
Position the measuring tool in one corner of
the room and position it so that the 0° laser
line runs parallel to the reference line (e.g.
wall). Measure the distance between the la-
ser line and the reference line directly at the
measuring tool and at the longest possible
distance from the measuring tool. Align the
measuring tool so that both distances are
identical.
Then measure at at least two different points
the distances 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.
Laying of square tiles (see figure B)
Position the measuring tool in one corner so
that the 0° laser line runs parallel to one
wall. Lay the first square tile at the crossing
point of the 0° and the 90° laser lines.
Laying with diagonal pattern (see figure C)
Position the measuring tool so that the 45°
laser line marks the diagonal tile joint.
Tile laying in kitchenettes (see figure D)
Firstly determine the height at which the first
tile row begins. Fix the measuring tool with
the levelling plate 10 vertically on the wall so
that the 90° laser line marks the lower edge
of the first tile row.
Laying from edges (see figure E)
Position the measuring tool on the levelling
plate 10 at the edge so that a lateral cut-out
11 of the levelling plate is directly at the
edge. The 0° laser line should run parallel to
one edge. The 90° laser line now marks the
lower tile row.
