FIELD: measurement technology. SUBSTANCE: in process of weighing standard weight is added many times to mass of weighed material, control instructions to final-control part of weighing system proportional to value and sign of mismatch signal between specified and present values of mass of weighed material are formed. For increase of precision indirect signal characterizing productivity of weighing machine, for instance, voltage applied to windings of electromagnets of vibration feeder is measured. On the basis of this signal additional signal on mass of material without standard weight is formed, Scaling factors of dependence between basic and additional signals are defined more exactly. Signal on mass of material without standard weight is predicted for each addition of this weight. EFFECT: enhanced precision of measurements. 6 cl, 2 dwg
