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.
