    a plurality of springs connected about the periphery of the said pan to a base and individually responsive to the pan'"'"'s position as a result of the load to be weighed being placed thereon;

    a plurality of sensors adapted to measure the load on said pan, positioned and connected between the pan and base, within the pan'"'"'s periphery;

    electronic means which measures the effect of pan movement on said sensors due to load off-center placement, which adjusts for spring and sensor manufacturing variabilities, and which calculates a resultant weight;

    means for calculating and entering adjustment coefficients for spring and sensor manufacturing variabilities into said electronic means; and

    means for outputting said resultant weight.
