A calibration device comprises a relative-value correction unit that performs a normalization for the measured output value based on a possible range of a measured output value and a normalization for a desired output value corresponding to the measured output value based on a range of the desired output value, an absolute-value correction unit that performs a normalization for the measured output value and the desired output value based on the range of the desired output value, a relative-value calibration unit that calibrates the measured output value normalized by the relative-value correction unit with reference to a characteristic of the desired output value normalized by the relative-value correction unit, and an absolute-value calibration unit that calibrates the measured output value normalized by the absolute-value correction unit with reference to the desired output value normalized by the absolute-value correction unit.
