Self-Levelling-System (SLS)
The AutoControl-Master ACM is of the
self-levelling kind. After it has been put
in the required basic position, fine
adjustment is being effected auto-
matically. Horizontal and vertical
orthogonal adjustments are effected by
the self-levelling system (SLS), while the
X-axis and the Y-axis are scanned by
two electronic measuring sensors. In
case the rotary laser has been tilted
by 90°, a third sensor levels the Z-axis.
The working angle is + 6°.
Anti-Drift-System (ADS)
The Anti-drift system (ADS) prevents
mismeasurements. Its principle of func-
tion: 45 seconds after ADS has been
activated, the laser is permanently being
checked for its correct adjustment.
In case the instrument has been moved
by external influences or the laser has
lost its frequency, the system switches
itself automatically off and the "tilt"-LED
shows a permanent light.
