Automatic Levelling

Position the measuring tool on a level, firm surface or attach it to the rotating platform (16) or the tripod (21).

For work with automatic levelling, slide the on/off switch (12) to the " On" position.

The automatic levelling function automatically levels irregularities within the self-levelling range of ±4°. The levelling is finished as soon as the laser beams stop flashing.

If automatic levelling is not possible, e.g. because the surface on which the measuring tool stands deviates by more than 4° from the horizontal plane, the laser beams will begin to flash quickly.

Place the measuring tool in a horizontal position and wait for self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±4°, the laser beams will light up continuously.

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 to avoid errors by moving the measuring tool.

For work with the pendulum lock, slide the on/off switch (12) to the " On" position. The laser ‌lines continuously flash slowly when working with the pendulum lock.

For work with the pendulum lock, the automatic levelling is switched off. You can hold the measuring tool freely in your hand or place it on a sloping surface. This means that the laser lines are no longer levelled and no longer necessarily run perpendicular to one another.
