When a Pass might not be a Pass

When you see a Pass with a * next to it, your test resulted in a Marginal Pass. What does this mean? For each test, there is an accuracy band above and below the limit line. If the result for one or more tests falls within that accuracy band, it is considered a marginal pass.

What should you do when you receive a marginal pass? That depends on the cable vendor's warranty or the contract you have with the customer. If either of those has specified that a marginal pass is not acceptable, you are going to need to troubleshoot the problem and fix it. If nothing is specified in the contract or warranty about marginal passes, then you could consider this a passing test result. If you are getting a number of these marginal results when you are testing your work, it might be a good idea to make sure you are using the correct test limits.
