renew feature. If you modify the acquisition or analysis parameters, the
application will prompt you to perform a new reference. For more
information, see Creating the Reference Traces on page 160.
During the tests, each result will be compared to those of the reference
trace.
You can specify the number of acquisitions that will be performed
during a learning cycle.
You can also set the application to start new learning cycles when
desired. The application can start the new cycle on a specific date or
periodically (for example, every 2 weeks).
Note: The application will only be able to start a new learning cycle if the
previous one has at least started.
You can even set the application to perform extra acquisitions when
the learning cycle is complete (extend). The application can start the
new acquisitions on a specific date or periodically until a certain
number of acquisitions is reached. This maximum value corresponds
to the number of acquisitions defined for a cycle plus the number of
extra acquisitions.
The learning process will be performed only if at least one test
program has been activated (enabled).
