Abstract
A method for calibrating a rotation angle sensor having a magnet, a magnetic detector disposed in a magnetic field of the magnet for outputting a detected value indicative of a direction of the magnetic field that varies in accordance with a rotation angle of a rotatable member, and an output circuit which transforms the detected value to an output value in accordance with a transforming characteristic and outputs the output value, the method entailing: assembling the magnet, the magnetic detector and the output circuit to a device that has the rotatable member; rotating the rotatable member to a predetermined reference angle; measuring the detected value or the output value as a measured value when the rotatable member is at the reference angle; and setting the transforming characteristic based on the measured value so that the output circuit outputs a reference output value at the reference angle.
