For example I have a test program. To test it I read all the results in.
Then set the test parameter to fail that number High, then low. Done. Another Test Runs in to a load Resistor. What if it is open? I added a test to insure the voltage drops. If your stuff is digital go no go, then checking both states says it is good. Analog is the same if the value changes from the idle range to the good range happiness. But it is your fixture. You have to look at what it does. Can a bad component or open wire cause a false pass. And what can you do to detect that? Example I have a 10V and 20V input test. There is no reasonable failure that will allow the test to pass with bad test fixture. It is always case by case. optimal is a test fixture tester. But where do you stop. |
