Abstract
An electronic scale apparatus for use in determining the net weight of an object placed on a weighing scale features selecting means operable for generating a digital signal corresponding to the dead weight of the object, digital to analog conversion means coupled to the selecting means and operable for producing a first analog signal corresponding to the digital signal, the weighing scale being operable for producing a second analog signal corresponding to the gross weight of the object, a differential amplifier coupled to the conversion means and to the weighing scale and being operable for producing a third analog signal substantially equal to the difference between the first and second analog signals, whereby the third analog signal represents the net weight of the object.
