AQL (Acceptable Quality Level)
Settings for production test are defined here. AQL is the level of test failures in
a batch that are acceptable. Exceeding the AQL is an indication that there is a
problem with the quality of the production process or the quality of materials
that are being used. AQL monitoring is an optional feature of the Voltech PC
Server, which displays live summary results from multiple AT testers. When
the AQL set here is reached or exceeded, the Server will display a warning.
Both types of AQL limits may be used at the same time. Reaching any one
limit will cause a warning to be displayed on the Server.
For further details, see the AT Server section of this manual.

Select this option to have the reports date and
time tagged.
This is the number of failures in the batch at which
a warning will be displayed on the Server. This is
most often used when the batch size is always
similar, or zero / very small numbers of defects
are expected.
This is the percentage level of failures at which a
warning will be displayed on the Server. Note that
this AQL is only applied after sufficient parts have
been tested to make the percentage meaningful.
When setting AQL % of Parts to be 1%, for
example, a warning will only be displayed after
100/1 = 100 parts have been tested.
Finally, you should enter a fixture name.
The Fixture ID can be up to 20 characters long.
You may use any of the characters that appear on
the tester's keyboard:
A ... Z (upper case only)
0 1 2 3 4 5 6 7 8 9 . - / ( ) and 'space'
