Abstract: Methods for correcting the level of a load cell in a weighing system are disclosed. An actual load value from N load cells of the weighting system is obtained and summed. Center of mass of the object to be weighed is calculated in an X and Y direction based on position coordinates of the N load cells. A load cell of the N load cells is selected and an ideal load value of the (N?1) load cells is expressed in terms of an ideal load value of the selected load cell. The ideal load value of each load cell is calculated based on a proportional relationship of the summation of the ideal load values of the N load cells and the summation of actual load value. The proportional relationship is based on a principle that the center of mass of the object to be weighed on a horizontal plane is constant. A load difference is calculated between the ideal load value and the actual load value of each load cell.
