Abstract

A method of determining a set of calibration values for offset-compensation of an inductive angular sensor arrangement includes: a substrate with a transmitter coil and three receiver coils, and a rotatable target. The method involves the steps of: a) exciting the transmitter coil; b) positioning the target at or near predefined positions, c) measuring and processing the signals, including calculating sums of squares of difference signals. A sensor device, and an angular sensor system may be arranged or adapted in view of the method.
