Abstract
Electronic scale including four feet, four strain gauges, an electronic control unit and a display, where the gauges are combined in pairs in first and second Wheatstone bridge type circuits, where a first intermediate-point of the bridge is selectively connected via a switch to an intermediate voltage source and where the first and second outputs of the amplifiers are summed by the electronic control unit in order to deduce therefrom a weight for an object present on the device, with indication for the user of off-center condition on the scale. Weighing method implemented in such a scale.
