Abstract
In a first correction process, a correction value T(0) is set as a median value between minimum and maximum correction values Tmin(0) and Tmax(0). A provisional adjustment value B=T(0)+Bini is input to the circuit section. A signal value output from the circuit section in accordance with the provisional adjustment value B is obtained by an A/D converter, and the magnitude relationship between the signal value and a target value is determined. When the signal value is smaller than the target value, a value that is smaller than the correction value T(0) by an error tolerance is set as a new minimum correction value Tmin(1). The median value between the minimum correction value Tmin(1) and the maximum correction value Tmax(1)=Tmax(0) is set as a next correction value T(1). In the next correction process, the provisional adjustment value B=T(1)+Bini is input to the circuit section.
