– Mark the centre of the 45 ° laser line at a distance of 

5 m  as  point 

VII

 as near as possible next to the point 

I

.

– The  difference 

d

 of the two points 

VII

 and 

I

 is the actu-

al deviation of the 0 ° laser line and the 45 ° laser line.

The measuring length 4 x 5 m = 20 m has a maximum 
admissible deviation of:  20 m x ±

0.4 mm/m* = ± 8 mm.

Therefore, the maximum difference 

d

 between the points 

I

 and 

VII

 may be 8 mm or less.

* The value ± 0,4 mm/m results from the angle accuracy 
±

0.2 mm/m plus a possible uncertainty of 0.2 mm/m 

while turning.

Working Advice



Always position the measuring tool flat on the floor 
or fix it flat on the wall. 

In case of uneven positioning 

or fixing, the angle is smaller than 45 ° and 90 °.



Always use the centre of the laser line for marking. 

The width of the laser line changes with the distance.



Never use the laser lines that the measuring tool 
standing on the floor projects on the wall for align-
ment. 

The measuring tool is not self-levelling. There-

fore, the line on the wall is distorted.



The reference point for the alignment of tiles is the 
crossing point P of the laser lines directly in front of 
the measuring tool. In order to mark an angle, the 
measuring tool has to be turned at this crossing 
point, see figure F.



Position the measuring tool only on a clean levelling 
plate 10. 

The measuring tool cannot stand level on an 

uneven, soiled levelling plate surface, which could lead 
to faulty measuring results.

Working with the levelling plate (see figures D – E)

Using the levelling plate 

10

 you can position the measur-

ing tool flat on an uneven or unstable floor. 

The levelling plate 

10

 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.

Positioning of the measuring tool on the levelling 
plate:

 Position the measuring tool with the magnets 

4

 on 

the underside on the levelling plate 

10

. 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.

Working with the laser target plate/ceiling measure-
ment plate (see figure A)

The laser target plate 

9

 or the ceiling measurement plate 

14

 improves the visibility of the laser beam under unfa-

vourable conditions and at longer distances.

The reflective part of the laser target plate 

9

 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 

14

 (accessory) can also 

be used for marking the laser lines. Like the laser target 
plate, it has a reflective and a transparent part.

Laser Viewing Glasses (Accessory)

The laser viewing glasses filter out the ambient light. This 
makes the red light of the laser appear brighter for the 
eyes.



Do not use the laser viewing glasses as safety gog-
gles. 

The laser viewing glasses are used for improved 

visualisation of the laser beam, but they do not protect 
against laser radiation.



Do not use the laser viewing glasses as sun glasses 
or in traffic. 

The laser viewing glasses do not afford 

complete UV protection 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 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.
