Date Feb. 21, 1980.A weighing balance to provide an average weight to an object which tends to move while being weighed such as a laboratory animal. The object to be weighed is placed on a receiving pan which provides an electrical analog output signal corresponding to the weight of the object. This signal after passing through an amplifier is converted to a digital electrical signal fed to a data input control means. A level detector setting means allows an output from said control means only when the weight on the balance reaches a predetermined level. The output from the control means is fed to a memory having a plurality of registers which store this information. Coupled on one side to this memory is a comparator which is also coupled on a second side to said control means. Also coupled to said comparator means is an allowable range means, sampling time means, and average calculating means. The average calculating means feeds an output to a printer.
