Abstract

Method of testing the functionality of condensate dischargers. Any ultrasonic vibrations present in the condensate discharger are picked up with an ultrasonic vibration sensor and transformed into an electric output signal. The latter is compared in an evaluation unit with stored data. A test result is then formed based on predetermined decision criteria. The test is carried out over a predetermined test duration, within which instantaneous values of the ultrasonic vibrations are picked up at predetermined times and, if need be, smoothed. The test result is based on the instantaneous values.
