Abstract

An arrangement that can be implemented with a simple circuit includes a measuring resistance that can either be connected in addition to a load or connected in place of the load. Furthermore, elements are provided that record the change in resistance resulting from the connection of the measuring resistance and signal when the change in resistance differs from a predefined value.
