摘要: The invention relates to a calibration method that can be carried out without reference system for an angle measuring device having code carrier (2) carrying absolute position code, and at least two reading heads (1a 1b) comprising fixed, known (4) angular distance, in particular of more than (50) degrees, relative each other, wherein one the distances between adjacent (1a,1b,1c,1d) differs from other distances, detecting partially, such value head determined carrier, rotated (3) heads, different positions thus captured, steps of: determining values setting; error by comparing difference location other; repeating plurality varying settings, performing mathematical analysis method, parameters function quantifying error, as or correction table derived parameters.
