ABSTRACT:
The present invention relates to an improved scale arrangement comprising three or more load cells which are compensated for both lateral and longitudinal displacement of the load on the scale platter or platform and to a method of accurately compensating the scale so that the output of the scale is independent of the position of the weight on the scale. Only two strain gages are provided for each load cell which gages are connected in a single bridge circuit. Compensating resistor networks are connected to at least certain of the strain gages.
