No responses so far, so I'll take a crack at it. You can see that it has a regular electrical plug, so it is most likely able to do the full testing of the condenser. There are a number of similar units out there (eBay, etc.) and I have to believe that they all work in basically the same manner. I would think a manual for any similar tester would go a long way getting you started with this. There is a manual for a similar unit on eBay, but it is overpriced. Perhaps someone on here has a similar unit with a manual they could copy for you.
