Abstract
A method and apparatus for calibrating load cells in the filed after the uncalibrated load cells have been installed. Two known weight conditions are used in conjunction with a storage device in which the uncalibrated load cells are installed. The method will calibrate the load cells, calculate load cell offsets, scale factor differences between load cells, and flexure/stresses in a supporting structure which rests upon the uncalibrated load cells.
