As you can see, the residual inaccuracy value (S1, S2, S3, and S4) depends on the radius of the measured
tool and approximately corresponds to 0.01 mm, for tools having a radius of 20 mm, while it is smaller than
0,001 mm. For radii that are bigger than 80 mm.
Based on these considerations, it is necessary to reach the best obtainable focus and after that search for the
maximum tangency, that is, the maximum measurement being displayed.
