摘要： In electronic balance, an analog computation portion determines at least a differential control signal according to an amount of displacement of a beam. A digital computation portion determines at least an integral control signal is determined by after the amount of displacement of the beam is digital-converted. The control signal component determined by the digital computation portion is analog-converted. Thereafter, a synthetic PID control signal is determined by being synthesized from a resultant signal and the control signal component, which is determined by the analog computation portion. Subsequently, a coil current based on the synthetic PID control signal is passed through the coil. A weight value is obtained according to the control signal component determined by the digital computation portion.
