摘要： PROBLEM TO BE SOLVED: To correct, by simple constitution, a deviated loading error caused by differences in spans of respective load cells due to positions of a weighed object on a mounting table.
SOLUTION: In this weighing device of the present invention, an estimation expression of a span coefficient is set in each of areas A1, A2, A3, A4 on the mounting table 11. When the weighed object is laid on the mounting table 11, a position of the center-of-gravity of the weighing object is measured based on outputs from respective load cells LC1, LC2, LC3, LC4 to determine the area within which the center-of-gravity is positioned, out of the areas A1, A2, A3, A4. A span coefficient is estimated using the estimation expression of the span coefficient set for the area where the center-of-gravity is positioned, and a weight of the weighed object is measured using the estimated span coefficient and total of the outputs form the respective load cells LC1, LC2, LC3, LC4.
