Automatic Levelling
To work with automatic levelling, position the measuring tool on a level and firm
support, attach it to the holder
16
or to the tripod
11
.
After switching on, the automatic levelling function automatically compensates
irregularities within the self-levelling range of ±4°. The levelling is finished as
soon as the laser lines do not flash anymore.
If automatic levelling is not possible, e.g. because the underside of the measur-
ing tool deviates by more than 4° from the horizontal plane or the measuring tool
is held freely in the hand, the laser lines will continuously flash slowly and the
measuring tool will work without automatic levelling. The laser lines remain
switched on, but the two crossed lines will no longer necessarily be at a right
angle to each other. To make sure that the two laser lines are still at a right angle
to one another, position the measuring tool orthogonal to the wall.
To work with automatic levelling again, position the measuring tool so that the
underside is aligned horizontally and wait for the self-levelling to be performed.
As soon as the measuring tool is within the self-levelling range of ±4° and is
levelled in, the laser lines will light up continuously again.
In case of ground vibrations or position changes during operation, the measuring
tool is automatically levelled again. Upon re-levelling, check the position of the
horizontal or vertical laser line with regard to the reference points on the wall to
avoid errors.
Working Advice
Always use the centre of the laser line for marking.
The width of the laser
line changes with the distance.
Attaching with the Holder (see figure A)
With the holder
16
, you can fasten the measuring tool to different objects rang-
ing in thickness between 10 and 60 mm, such as vertical or horizontal boards or
pipes.
