# Automatic Levelling

## Overview

The measuring tool will automatically detect the horizontal or vertical position. To change between the horizontal and the vertical position, switch the measuring tool off, reposition it and switch it on again.

After switching on, the measuring tool checks the horizontal and vertical position and automatically levels out any unevenness within the self-levelling range of approx. ±8 % (±4.6°).

During levelling, the status indicator (3) flashes green, the laser does not rotate and flashes.

The measuring tool is levelled in as soon as the status indicator (3) lights up green continuously and the laser lights up continuously. After levelling is completed, the measuring tool automatically starts in rotational operation.

When the measuring tool is out-of-level by more than 8 % after switching it on or after a position change, levelling in is no longer possible. In this case, the rotor is stopped, the laser flashes and the status indicator (3) continuously lights up red.
Reposition the measuring tool and wait for it to re-level. Without repositioning, the laser is automatically switched off after 2 minutes and the measuring tool after 2 hours.

When the measuring tool is levelled in, it continuously checks the horizontal and vertical position. Re-levelling is automatically performed if there are any position changes. To avoid faulty measurements, the rotor stops during the levelling process, the laser flashes and the status indicator (3) flashes green.

## Shock-Warning Function

The measuring tool has a shock-warning function. After position changes or shock to the measuring tool, or in case of ground vibrations, it keeps the measuring tool from levelling in at changed positions, and thus prevents errors caused by a change in the measuring tool's position.

Switching on/activating the shock-warning function: Press the shock-warning button (2). The shock-warning indicator (1) lights up green continuously. The shock warning is activated approximately 30 seconds after the shock-warning function has been switched on.

Shock warning actuated: If the levelling-accuracy range is exceeded when changing the position of the measuring tool or a severe knock is registered, the shock warning will be actuated. The laser will stop rotating, the laser beam will flash, the status indicator (3) will go out and the shock-warning indicator (1) will flash red.

The current operating mode is stored.

After the shock warning has actuated, press the shock-warning button (2) on the measuring tool or the shock-warning reset button (22) on the remote control. The shock-warning function is restarted and the measuring tool starts the levelling. As soon as the measuring tool is levelled in (levelling indicator (3) continuously lights up green), it starts in the stored operating mode.

Now check the position ‌of the laser beam at a reference point and, if necessary, correct the height or alignment of the measuring tool.

When, after the shock-warning function has actuated, the function is not restarted by pressing the shock-warning button (2) on the measuring tool or the shock-warning reset button (22) on the remote control, the laser is automatically switched off after 2 minutes and the measuring tool after 2 hours.

Switching off the shock-warning function: Press the shock-warning button (2) once or, when the shock warning has actuated (shock-warning indicator (1) flashing red), press it twice. When the shock-warning function is switched off, the shock-warning indicator goes out.

Note: The shock-warning function cannot be switched on or off with the remote control; it can only be restarted after having actuated.
