To activate the automatic switch-off, switch the measur-
ing tool off and switch it on again by pressing briefly the 
On/Off button

. After the switching on, the laser lines do 

not flash.

Angular accuracy

Influences on Accuracy

The ambient temperature has the greatest influence. Espe-
cially temperature differences occurring from the ground 
upward can divert the laser beam.

Therefore, position the measuring tool as near as possible 
to the work surface and fix it with the underside as parallel 
as possible to the work surface.

Apart from exterior influences, device-specific influences 
(such as heavy impact or falling down) can lead to devia-
tions. Therefore, check the accuracy of the measuring tool 
each time before starting your work.

Checking the angular accuracy

For this check, you need a free surface of approx. 
10 x 5 m on a stable and even base.

Should the measuring tool exceed the maximum deviation 
during one of the tests, please have it repaired by a Bosch 
after-sales service.

Checking the angular accuracy between  the 0 ° and 
the 90 ° laser lines

– Position the measuring tool in one of the corners of the 

measuring surface. Switch on the measuring tool and 
align it so that the 0 ° laser line runs along the long side 
of the measuring surface and that the 90 ° laser line 
runs along the short side of the measuring surface.

– Mark the crossing point of the laser lines on the floor 

(Point

I

). Mark also the centre of the 0 ° laser line at a 

distance of 5 m (Point

II

) and at a distance of 10 m 

(Point

III

).

– Position the measuring tool (without turning it) at a dis-

tance of 5 m so that the crossing point of the laser lines 
is on the already marked point

II

 and that the 0 ° laser 

line runs through the point

III

.

Mark the centre of the 90 ° laser line at a distance of 
5 m  (Point

IV

).

– Turn the measuring tool by 90 ° so that the centre of the 

0 ° laser line runs through the point

IV

.

The crossing point of the laser lines must still be on the 
point

II

.

– Mark the centre of the 90 ° laser line at a distance of 

5 m  as  point

V

 as near as possible next to the point

I

.

– The difference 

d

 of the two points 

V

 and 

I

 is the actual 

deviation of the 0 ° laser line and the 90 ° laser line from 
the right angle.

The measuring length 2 x 5 m = 10 m has a maximum 
admissible deviation of: 10 m x ±

0.2 mm/m = ± 2 mm.

Therefore, the maximum difference 

d

 between the points 

I

 and 

V

 may be 2 mm or less.
