Protractor with offset compensation and method for compensation of the offset drift of a protractor

The invention relates to a method of compensating an offset drift of an angle sensor and an angle sensor with offset compensation, which determines an angle to be measured on the basis of a respective sine signal and cosine signal. A particularly simple method for offset compensation is, first, the amplitude (A) of the cosine and / or sin signal to detect and determine the corresponding offset value on the basis of the amplitude value determined (A). Thus, the SiN generated by the protractor and cos signals, and thus the angle measured value can be corrected.
