Example:
Measurement range 50 mm, voltage output 0 ... 10 V
Master value 17 mm, related to the centre of the measurement range (MR) = 5 V,
Analog value during mastering: 3.4 V
After the mastering, the sensor gives new measurement values, related to the master value. The non-mas-
tered condition applies by means of a reset.
