A delay section 43 delays (a delay time is equal to a time required for processing carried out through the control section 21) an analog measurement signal outputted from a D/A converter 42 to output a delay measurement signal. A delay section 43 delays (a delay time is equal to a time required for processing carried out through the control section 21) an analog measurement signal outputted from a D/A converter 42 to output a delay measurement signal. A subtractor 44 subtracts an analog delay measurement signal outputted from a delay section 43 from an analog measurement signal outputted from a D/A converter and outputs a subtraction signal.  An adder 46 adds an analog control signal outputted from a D/A converter 23 and a subtraction signal amplified and controlled by an amplifier 45 together and outputs an addition signal.
