  • Page 24 7 Working with the MLS 508 7.3.3 Relative adjustment of the Cross Slope sensor Via the relative adjustment the Cross Slope sensor’s actual value can be re- adjusted. It is of no importance whether this is done in manual or automatic mode. 1) Press and hold the function key F2 in the standard working menu.
  • Page 25 7 Working with the MLS 508 7.4 Zero adjustment Before describing operations with the various grade sensors, the term “zero adjustment” has to be defined. For every new application or after mounting or remounting a grade sensor, the current value measured by the sensor has to be adjusted to zero. In doing so, the current mounting level of the grade sensor above the reference is saved in the system and a clear reference value is provided for all future target values at the same time.
  • Page 26 7 Working with the MLS 508 The current value measured by the grade sensor (actual value) is taken over as target value and both values are assigned the value 0.0. There is no deviation. All measurements after the zero adjustment refer to this height. Alternatively the zero adjustment can be carried simultaneously...
