PURPOSE: To enhance weighing accuracy, by arranging an electronic computing circuit so as to renew a memory code only when an addend of a present combinatory code is smaller than the obtained value most approximate to the previous set weight value.
CONSTITUTION: Outputs α, β from the first, and second adders F, G of an electronic computing circuit are applied to comparator I as absolute values of a remainder of set value α0 subtracted by an addend α=α0-FX, β=β0-GX. Comparator I renews the memory code of addition code memory circuit J only when α< β. When calculations of all the combinations in one time calculation completes, a calculation end signal is produced, read-out circuit K reads out the memory addition code of circuit J, only weighing hopper B corresponding to the code number of this memory code is opened via a code discrimination circuit, etc., the weighed material is collected in pool hopper D, and placed in bucket E. High precision weighing is thus carried out.
