Non-linearity error (% F.S.*)

The non-linearity error represents the largest difference between the calibration curve and a straight line, called the "best straight", connecting the output signal to the applied force.

This line can be established either between the zero load signal and the nominal capacity signal or another more operational value, such as 75% of the nominal load to share the error. In some cases, it can also be obtained by the least squares method.

This error is expressed in % of the full scale.
