ABSTRACT:
A weighing apparatus of the tare-type is disclosed including a subtractor connected between the weighing scale output and an indicating device, a first tare store being provided having an input connected by a taring switch with the weighing scale output, and an output connected with a second input of the subtractor, characterized by the provision of an auxiliary tare store connected with the first tare store via a transfer switch that is ganged for operation generally simultaneously with the taring switch, thereby to transfer the first tare signal to the auxiliary store. An erasing switch is operable, as desired, to return the first tare signal from the auxiliary store to the first tare store. The taring and transfer switches are so operable that the closing of the contacts of the taring switch is delayed relative to the closing of the contacts of the transfer switch, whereby the first taring signal in the first tare store is transferred to the auxiliary store before a subsequent weight signal is supplied to the first tare store.
