The circuit (38) has a sensor component (14) for measuring electric current (Im) flowing through a conductor (22) by measuring input voltage between input lines (55, 56) of the sensor component. A sensor controller (18) controls the sensor component, and the sensor component has a sensor device (51) for detecting intensity of the electric current by using an analog-to-digital converter (41) for converting analog measuring values (Ue1) into digital measuring values (U1d). An input (55a) of the converter is connected with one of the input lines over a connecting impedance (Z1). An independent claim is also included for a method for monitoring functionality of a current measuring circuit. |
