Abstract
A self-testing measuring system includes at least three modes: an operating mode and at least two test modes. In a third test mode, a digital signal generating unit stimulates the digital input circuit directly by means of test signals. In a second test mode, the digital signal generating unit stimulates the analogue signal string and the digital input circuit by means of test signals. In a first test mode, the digital signal generating unit stimulates the analogue signal string, the measuring unit (typically an ultrasound transducer) and the digital input circuit by means of test signals, thereby allowing this signal string to be tested. In the operating mode, the digital signal generating unit stimulates the analogue signal string, the measuring unit (typically an ultrasound transducer) and the digital input circuit by means of output signals, thereby allowing the signal string to be monitored for parameter compliance.
