Abstract

PURPOSE: To correct in a simple manner with high accuracy by cutting a part of a distorsion generating body corresponding to a measuring point in the circumference of a measuring reference point when an output value at said measuring point is different from a measuring value at said measuring reference point thereby to make correction of errors.
CONSTITUTION: The relation between a reference load and an output value at a measuring reference point 11 which is preliminarily set among the free ends is determined. At the same time, the relation between the load and an output value at each of the other points in the circumference of the reference point 11, that is, eccentric load points 12a-12d is determined. When the output value at the eccentric load points 12a-12d is different from the measuring value at the reference point 11, a part of a distorsion generating body 1 is cut corresponding to the eccentric load point to correct errors. Therefore, the distorsion generating body 1 deforms minutely corresponding to a part thereof to which the load is applied, and the deformation of a distorsion sensor 4 becomes constant. Accordingly, errors can be corrected easily with high accuracy.
