Beschreibung
Zusammenfassung:	A method for operating an inductive conductivity meter having a transmitting coil, a receiving coil and a terminating impedance device, the transmitting coil having a transmitting coil terminal, the receiving coil having a receiving coil terminal and the terminating impedance device having a terminating impedance, wherein the receiving coil is terminated with the terminating impedance device and wherein the transmitting coil and the receiving coil are inductively coupled with one another by an electrically conductive medium. To provide an improved accuracy of a determination of a conductivity of a medium a setpoint input impedance is specified, an input impedance is determined at the transmitting coil terminal, the terminating impedance is set such that the input impedance is matched to the setpoint input impedance, and a conductivity of the medium is determined using the adjusted input impedance and the set termination impedance.
