6.3.3 Stop On Fail
‘Stop on Fail’ is another program option that is either enabled or disabled when the program is created (see Chapter 3 - ‘The Test Program Editor’).
When enabled, it will cause the measurements to be terminated after each test which has produced a ‘Fail’ result. A display similar to one of the following will then be seen:
| 1 |
Part name / number. |
| 2 |
Failing test number. |
| 3 |
Graphical qualification of the failure showing the value measured with
respect to the range of legal values, where:
Box – Represents the legal limits for the test
Vertical bar – Represents the value measured. (Replaced by an
arrowhead to represent higher or
lower, when the measured value is
significantly outside of the legal range – see notes below.) |
| 4 |
Value measured, with appropriate units. |
| 5 |
Available soft-key functions. |
Note:
The third line showing the graphical comparison of the measured value and test limits has a logarithmic scale. The measured value may be represented by either a vertical bar (as shown) when it lies within the range that can be displayed on the LCD, or by an arrowhead (< or >) at the end of the horizontal bar when it lies outside the range that can be displayed on the LCD.
Pressing the ABORT soft-key stops the program and allows the operator to discard the failing component at the earliest opportunity to minimise test times. (The ABORT is also reported to the server when the program option 'Send retry results to server' is enabled and printed out, when a results printing option is set.)
After pressing the CONTINUE soft-key, the remaining tests in the program will be executed. ‘Stop on Fail’ will remain active, and any subsequent test that also fails will produce a similar display. At the end of the measurement, the component will be classed as a ‘Fail’.
Pressing the RE-RUN soft-key will re-start the test sequence from the beginning.
Note: You would normally press RE-RUN if the failure was caused by the component being incorrectly inserted into the fixture. Unless the option ‘Send retry results to server’ is enabled, at this point there will be no data sent back to the server. Therefore, after you have corrected the mistake, following the re-run, good transformers will be reported as ‘Pass’.
