Claim 0:
1. A method of testing an impedance-sensitive system with a switching device, the switching device comprising an input connection configured to connect to a coil electronics system and/or to a resonant circuit capacitor, an output connection configured to connect to an end of a coil and/or to the resonant circuit capacitor, and a disconnecting device comprising a switch and an impedance connected in parallel, the disconnecting device being switchable between an on-state and an off-state using the switch, wherein in the on-state the disconnecting device is configured to connect the input connection and the output connection to an on-impedance when the switch is closed, wherein in the off-state the disconnecting device is configured to connect the input connection and the output connection to an off-impedance determined by the impedance connected in parallel when the switch is open, wherein the off-impedance has an increased value compared to the on-impedance, permitting a current flow between the input connection and the output connection while damping an external positioning signal of a definable frequency that couples into the coil so as to reduce undesirable oscillations of the coil, the method comprising:
switching the disconnecting device into the on-state configured to permit transmission of energy via the coil;
implementing a first measurement with the impedance-sensitive system;
switching the disconnecting device into the off-state configured to permit damping of the external positioning signal that couples into the coil so as to reduce the undesirable oscillations of the coil;
implementing a second measurement with the impedance-sensitive system;
performing a comparison of the first measurement and the second measurement;
performing a verification of the comparison with a target specification; and
displaying a correct function and/or a malfunction depending on the verification.
