Automatic Levelling

To work with automatic levelling, place the measuring tool on a level, firm sup-
port or fasten it to the tripod 3.
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 measuring
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 meas-
uring 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 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 lev-
elled 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 in again. To avoid errors, check the position of the hor-
izontal and vertical laser line with regard to the reference points upon re-levelling.

Working Advice

 Always use the centre of the laser line for marking. The width of the laser
line changes with the distance.
Working with the Markings on the Laser Lines (see figures A–B)
Markings are displayed at equal intervals on the laser lines, which can be used to
assist with orientation. The intervals between the markings are equal only when
the measuring tool is aligned perpendicular to the wall. You can check the 90°
angle using the laser target plate 9.
Place the measuring tool in the required position, switch it on and allow it to level
in. Place the laser target plate 9 with its back against the wall. Align the measur-
