There is described a position sensor having a first channel that produces a first position signal which varies with position in the measurement range in accordance with a first measurement function modified by a first error function, and a second channel that produces a second position signal which varies with position in the measurement range in accordance with a second measurement function modified by a second error function. The position sensor determines first calibration data by processing the first and second position signals at different positions within the measurement range, the first calibration data at least partially compensating for the first error function. The position sensor can subsequently process the first position signal, using the first measurement function and the first calibration data, to generate an output that more accurately represents position. In an embodiment the position sensor may also determine second calibration data that at least partially compensates for the second error function. |
