ABSTRACT:
A calibration process for setting the switching point of a sensor which produces an output signal depending on whether a switching point has been exceeded or has not been reached by a sensor signal produced by a condition being sensed exceeds the switching point, and in which the value of the switching point is determined using the values of the sensor signal in the uninfluenced and in the influenced state. Operating reliability of the sensor is improved by determining the location of the switching point during the calibration process under the condition of essentially identical operating reserves of the sensor in the uninfluenced and in the influenced state.
