ABSTRACT:
The sensitivity of two or more load elements and associated strain gauges supporting a platform are equalized by the progressive removal of material at a location which essentially changes the rigidity of the securement of one of the load elements and its associated strain gauges until equalization results. By making the sensitivities of all of the load elements and their associated strain gauges the same, the output signal reading indicating a load will be the same for center and off-center positions of the load on the platform.
