A method for installing a stroke sensor is provided such that the stroke sensor can be easily adjusted using a simple process. The method has the steps of; obtaining a relationship between the magnetic field and the indicator value while moving the magnet in the first direction relative to the magnetic field detecting element within a predetermined relative movable range, and writing the relationship in the processor; after the relationship is written in the processor, preventing the predetermined relative movable range from being shifted in the first direction by means of a jig for preventing positional shift, wherein the jig includes an element that fixes relative positions between the magnetic field detecting element and the magnet; attaching the magnet and the magnetic field detecting element, which have been prevented from being shifted, to different structures that are movable in the first direction relative to each other, and removing the jig.

A method for detecting an error in a bridge sensor which is adapted for measuring a physical parameter. The method comprises biasing a first contact pair of the bridge sensor 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 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 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.
