Abstract:
In a method for functional testing of a mechanical vibration sensor, a vibration signal is generated on the vibration component of the vibration sensor with the aid of a periodic excitation signal, the frequency of which excitation signal is varied, and a post-vibration process of the vibration component of the vibration sensor is analyzed once the excitation signal has been switched off.
