Abstract: A method operates a measuring device used to determine a fluid variable. The measuring devices contains a vibration transducer driven to excite a wave in the fluid due to a test excitation signal. The wave is guided along a propagation path back to the vibration transducer or to an additional vibration transducer, thereby exciting the (additional) vibration transducer to vibrate. An output signal relating to this vibration is acquired, and a frequency of that segment of the output signal that lies in an analysis interval is determined. The analysis interval starts once the driving of the vibration transducer to excite the wave has finished, and/or once a maximum of the amplitude of the vibration is reached. The determination of the fluid variable is performed based on the determined frequency. An error message or a notification is output to a user and/or to a device external to the measuring device.
