Abstract

The invention relates to a method for determining the electrical resistance of an electrical supply lead to sensor elements and concerns a sensor arrangement. The sensor elements are interconnected to form a sensor arrangement, and the electrical total resistance of the supply lead to the sensor elements is determined by effecting a measurement involving an electrical component. The electrical total resistance of the supply lead to the sensor elements is compared to a reference value, whereby the reference value is the value of the electrical total resistance of a reference component of the circuit arrangement and of its electrical leads. The reference value is also determined by effecting a measurement.
