way to rework the characteristics of the bore to make it fit in the tolerance interval.
However, if the bore is too small, it can still be increased, and then the part could fit in
the tolerance interval. In this case, the internal diameter is used, as on the pictures
bellow.
On the measuring screen, a yellow indicator shows when the part is too small (so
possible to rework), and a red indicator if the part is too big (rejected)
REWORK PASS REJECT
Direction: External diameter
The opposite phenomena happens for the external diameter.

This screen allows to set tolerances and the characteristics (nominal and master)
Just press on the corresponding edit box to input the needed values
The tolerances must be set relatively from the nominal value
Example : diameter 8mm +/-20µm
 upper tol : 0.020
 nominal : 8
 lower tol :-0.020
 master : real value according to the calibration certificate.
