Summary:A method for operating a Coriolis measurement device comprises the following steps: recording the measured voltages of sensors for sensing measuring tube vibrations and creating an asymmetric sequence of values by way of the amplitudes of the measured voltages for the purpose of diagnosing the Coriolis measurement device, recording at least one stabilization variable and creating a stabilized asymmetric sequence of values based on the stabilization variable, wherein the stabilization variable is one of the following variables or a first or further temporal derivative thereof: a resonant frequency of the measuring tube containing medium or a variable derived therefrom, time or phase difference between measurement signals from the first sensor and the second sensor or a variable derived therefrom, temperature of the measuring tube wall, temperature difference between two measurement points of the measuring tube wall.
