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.

Calibration process for setting a switching point of a sensor which produces an output signal depending on whether or not a sensor signal produced by a condition being sensed exceeds the switching point, comprising the steps of producing values of the sensor signal in an uninfluenced state and in an influenced state, and setting the switching point at a value at which an operating reserve of the sensor occurring in the uninfluenced state is approximately identical to an operating reserve occurring in the influenced state, at least for weak influences on the sensor.
