Abstract

A method for operating an inductive conductivity-measuring cell having a primary circuit with a sending coil, a secondary circuit with a receiver coil, and a short-circuit path, which passes through the sending coil and the receiver coil. The sending coil couples via the short-circuit path inductively with the receiver coil, wherein, in the case of closed short-circuit path, a first electrical signal present in the primary circuit is measured, and wherein the first signal is compared with, and/or weighed against, values, which are furnished or stored.
