Manostat has the following parts to comprise: 1, adjust circuit; 2, sampling circuit; 3, sampling enlarge; 4, fiducial circuit; Stabilized voltage process: Set output voltage to already was achieved set voltage beforehand. When output voltage changes, sampling circuit obtains enlarge of example classics sampling and fiducial circuit to judge output voltage quite is to change high or to low change, judge metabolic quantity, control from this adjust circuit job, make adjust circuit to adjust output voltage to low or tall change, achieve till output set voltage beforehand.
