Optimizing Ascertain the optimum setting of the tolerance especially with
critical conveyed parts in the test mode. Use one of the
following methods:
S Empirical setting
Vary the tolerance so that the test of a large number of
parts produces correctly recognized good and bad parts.
S Setting corresponding to inspection part deviation:
S Select sample parts which are suitable as reference
for good or bad parts. The recognition-specific
features should lie if possible in the limit range
good/bad.
S Vary the tolerance so that the following test part devi-
ation is shown when the limit sample part is scanned:
‹ 100 limit sample part “Good”
› 100 limit sample part “Bad”
