ABSTRACT:
A circuit arrangement and a method are described with which a current circuit can be monitored for correct function. A first and a second current sensor are provided in the current circuit. In a test phase, the second current sensor is switched to the current circuit. Next, a current flow is brought about through the first and the second current sensors, and the current intensity is measured via the first and second current sensors. From a comparison, an error function of the current sensor can be detected. The circuit arrangement according to the invention and the method according to the invention are particularly suitable for use in safety-oriented equipment.
