ABSTRACT:
A measuring bridge arrangement has a measuring bridge with a first supply terminal and first and second measuring signal terminals. The measuring bridge arrangement has a working point adjustment circuit formed to feed the measuring bridge via at least the first supply terminal in a measuring state of operation, and to apply a signal to one of the measuring signal terminals in the test state of operation in order to bring the measuring bridge to a test working point different from a measuring working point in the measuring state of operation. The measuring bridge has a test tap, wherein a test signal dependent on resistive properties of at least one element of the measuring bridge can be tapped at the test tap of the measuring bridge.
