1. Method for operating a resonance-measuring system wherein the resonance-measuring system includes at least one oscillation element, at least one oscillation driver and at least one oscillation sensor, comprising the steps of:

  • exciting the oscillation element to oscillation in at least one eigenform from at least one control in at least one control loop by at least one oscillation driver excited by at least one excitation signal Fi(t)detecting the excited oscillations of the oscillation element with the oscillation sensors as at least one response signal yi(t),varying at least one set variable of the closed loop in a pre-determined manner, andselectively identifying at least one parameter of the excited eigenform by evaluating at least one of at least one resulting excitation signal Fi(t) and at least one resulting response signal yi(t) with the help of a mathematical model of the resonance-measuring system.
