Automatic Levelling

Position the measuring tool on a level, firm surface or attach it to the universal holder (25) or the tripod (31).

For work with automatic levelling, slide the on/off switch (16) to the " On" position.

The automatic levelling function automatically compensates irregularities within the self-levelling range of ±4°. 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 4° from the horizontal plane, the laser lines will begin to flash quickly. If the signal tone function is activated, rapid signal tones will sound.

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 and the signal tones will cease.

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 (16) to the " On" position. The pendulum lock indicator (4) lights up red and the laser lines continuously flash slowly.

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.
