Abstract

A device for the determination of a measured variable, a motion variable in particular, is described. At its output, the device signals a malfunction via a fixed voltage level at the output. The device includes a self-test module that functions concurrently with a measurement operation without external triggering and interrupting or interfering with the actual measurement.
