Patent ID: 7742891

Claim:
A method of correcting for errors in a load cell, comprising the steps of: a. measuring load cell deflection under increasing loads; i. determining an increasing load curve; b. measuring load cell deflection under decreasing loads; i. determining a decreasing load curve; c. determining a measured load cell deflection after one of, either; i. increasing the load on the load cell; or ii. decreasing the load on the load cell; d. correcting the measured load cell deflection by applying the measured load cell deflection to, either; i. the increasing load curve in the event that the determining step occurred after increasing the load on the cell; or ii. the decreasing load curve in the event that the determining step occurred after decreasing the load on the cell; e. determining a corrected load and thus compensating for error in the load cell related to increasing or decreasing loads; and f. compensating for temperature changes in the load cell by applying a temperature formula to the measured load cell deflection, the temperature formula correlating the temperature of the load cell with the measured deflection of the load cell under various loading conditions.
