Insulation Compression Failures
If you are experiencing shorts or high voltage testing failures, check if your cables or wires are being compressed with clamps or tight-fitting...
When a test fails and the reason isn't clear, it can be tempting to jumpt to conclusions. Is something in the tester broken? Is the software malfunctioning? The tester can be the first thing to blame because you have little or no contol over the state of the maching.
In order to find the cause of the failure, you need to consider the problem might be located somewhere other than the tester.
One of three things usually cause a failure:
- Cable
- Fixturing
- Tester Interface
You can test each possible cause until you pinpoint the true reason for the failure.
Cable
Test another similar cable using the same test program as the failed cable. If the new cable passes, it probably means your original cable has an error.
Fixturing
Test the fixturing without the test cable attached. If the test fails, it could mean the error lies in the fixturing.
Tester Interface
If you’ve tested both the cable and the fixturing for errors, the problem may be with the tester interface. If you suspect there is a problem with your Cirris tester, contact tech support.
