6.4 Assessing the test results
6.4.1 Visual check
Check the test results e.g. according to the following aspects:
– Have the orientations been recognized correctly?
– Is the grading of the parts recognized as good/bad
correct?
Use the sample parts to check the test parts with regard
to their grading. If you have also checked faulty parts,
check whether these have actually been recognized as
bad.
– Use as many test parts as possible to make sure that they
are correctly output at the delivery positions for good,
bad or incorrectly orientated parts.
Observe the explanations on the test procedure in the next
chapter. If necessary, optimize the test result via the influence
of the tolerance (chapter 6.3).
6.4.2 Checking the features
The individual features of the test parts differ from the aver-
age values of the sample part features. The Checkbox ascer-
tains for each test part the feature which deviates the most
(maximum deviation).

During the test procedure the test part deviation will be dis-
played for 1.5 seconds. Detailed instructions on the test part
deviation (computational algorithm) can be found in chapter
A.3.3.
