Sensor Automatic
The rotary laser aligns itself automatically. It is set to the required initial position (to
within an operating angle of ± 4°) and the automatic system then performs the neces-
sary fine adjustment, with three electronic measurement sensors detecting the X, Y and
Z axes.
Anti-Drift-System (ADS)
The anti-drift system (ADS) prevents erroneous or inaccurate measurements. How it
works: continuous monitoring of the alignment of the laser is activated 30 seconds after
the ADS is switched on. If the device moves due to the influence of external factors or
the laser loses its height reference, the laser will come to a standstill. The laser and the
tilt LED also start to flash rapidly. The device has to be switched off and on again in
order to continue using it. Erroneous and inaccurate measurements are thus prevented
simply and reliably. IMPORTANT: The ADS is not active following switch-on. Once the
device has been set up, press the tilt button to activate the ADS, enabling you to protect
the laser from changes in position caused by the device being disturbed by external
factors. The tilt LED flashes to indicate that the ADS function is active; see the diagram
below.

Attention:
The ADS does not activate the monitoring function until 30 seconds after the laser
levelling procedure has been completed (set-up phase). The tilt LED flashes every
second during the set-up phase and flashes more slowly when the ADS is active.
