VOLTECH AT3600 USER MANUAL TEST RESULTS HANDLING
Results may also be exported or printed using the normal options found under the file

AQL
AQL (Acceptable Quality Level) settings for production test are defined for each
program using the Editor. AQL is the level of test failures in a batch that are
acceptable. Exceeding the AQL is an indication that there is problem with the quality
of the production process or the quality of materials used. AQL monitoring is an
optional feature of the Voltech PC Server which displays live summary results from
multiple AT testers. When the AQL level set here is reached or exceeded, the Server
will display a warning.
'AQL No. of Parts' 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.
'AQL % of Parts' 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.
Both types of limit may be used at the same time. Reaching any one limit will cause a
warning to be displayed on the Server.
When an AQL level is reached or exceeded the Server will display a warning:
Click on 'OK' to acknowledge the warning. You will be given the option to disable
the warning for further parts in the batch. Normally, you would select 'No' to leave
the AQL checking active for the rest of the batch. When a new batch is started, the
AQL level is reset according to the level entered for the part using the Voltech AT
Editor.
