Abstract

A method (400) for detecting an error in a bridge sensor (100) which is adapted for measuring a physical parameter. The method comprises biasing (410) a first contact pair of the bridge sensor (100) at least two times in a first direction and at least one time in a second direction opposite to the first direction; while biasing the first contact pair, measuring (420) an output signal on a different contact pair of the bridge sensor, thus obtaining at least three output measurements which are representative for the physical parameter and which are separated by time intervals; combining (430) the output measurements to obtain an output value which is indicative for an error in the bridge sensor, wherein the output measurements which are combined are only those output measurements which are measured when biasing the first contact pair.
