Automatic Levelling

Position the measuring tool on a level, firm surface or attach it to the rotating platform (12).

For work with automatic levelling, slide the on/off switch (7) to the " On" position.

The automatic levelling function automatically compensates irregularities within the self-levelling range of ±2.5°. The levelling is finished as soon as the laser lines stop moving.

If automatic levelling is not possible, e.g. because the surface on which the measuring tool stands deviates by more than 2.5° from the horizontal plane, the laser beams will flash quickly.

If this is the case, set up the measuring tool in a level position and wait for the self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±2.5°, 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 levelling, check the position of the laser beams with regard to the reference points to avoid errors arising from a change in the measuring tool's position.

For work with the pendulum lock, slide the on/off switch (7) to the " On" position. The pendulum lock indicator (14) lights up red and the laser lines continuously flash slowly.

For work with the pendulum lock, 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 beams are no longer levelled and no longer necessarily run perpendicular to one another.
