description A method for operating a Coriolis measurement device comprises: recording the measured voltages from the sensors and creating an asymmetric sequence of values using the amplitudes of the measured voltages for the purpose of diagnosing the Coriolis measurement device; checking whether the asymmetric sequence of values satisfies at least one invalidity criterion; and creating a stabilized asymmetric sequence of values on the basis of the asymmetric sequence of values by replacing asymmetric measured values with substitute values. While an invalidity criterion is satisfied a last valid measured value of the asymmetric sequence of values is used as the current value of the stabilized asymmetric sequence of values, or the stabilized asymmetric sequence of values is set to a predetermined value, a first invalidity criterion being based on a scattering parameter of the asymmetric value exceeding a first limit value.
