Special product features and functions
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 necessary fine adjustment, with three electronic
measurement sensors detecting the X, Y and Z axes.
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. Additionally, the laser flashes and the tilt
LED is lit continuously. To continue working, press the tilt button again or switch
the device off then on again.
The ADS is not active following switch-on. Once the device has
been set up, press the tilt button to activate the ADS. The tilt LED flashes to
indicate that the ADS function is active; see the diagram below.
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, rapid
flashing, when ADS is active.
