A digital weighing scale is compensated for the effects of off-center loading by determining the position of the load and calculating a corrected weight value according to such position. Position sensing transducers (16,17) are mounted on the load cell to provide information regarding the position of the load on the weighing scale. An expression for corrected weight as a function of load position and magnitude is determined for the particular scale and stored. The expression is used to calculate corrected weight according to the magnitude and position of each weight placed on the scale. The load cell may include a counterforce of substantially any type including single bending beam, dual bending beam or capacitive structure, and the load magnitude and position sensors may be of substantially any type including strain gages and capacitive sensors. |
