【Abstract】 In this paper,principle of measurement of highaccuracy elect-ronic balance is discribed.In the meantime,error analysis is given in deatil.the compensating A/D converted technique is developed in the measuringcircuit.In the data processing,we use digital filtering estimation,self-corr-ecting,as well as auto zero-point follow-up’s control method,with these tec-hniques,we have achieved such good stability and ability of recurreuce andfollow-up of the electronic balance.更多还原
