ABSTRACT:
A method for measuring the dew point according to patent application P 36 33 015 is expanded so that an automatic zero point correction can be carried out. For this purpose, the heating power on the heating device is raised to a point, at which the dew evaporates and the sensor-specific property, for example the capacity, is measured and supplied to the evaluating unit as a calibration signal.
