Abstract
A scale construction comprises a pair of spaced substantially rigid plates offset with respect to each other and supported by means of flexure members extending therebetween. A strain gauge is carried between the plates. In one embodiment a flexure member carries the strain gauge means. Electrical bridge circuitry coupled to the strain gauge supplies a digital display of the weight supported on the top plate. In addition, one of the legs of the bridge circuitry is adjustable so as to be able to provide a representation that there is zero weight on the top plate when all weight has been removed therefrom in order to calibrate the scale.
