Where do i find the pdf manual for this product?

This site might help you out. Otherwise I would be OK with copying mine and emailing it to You. https://www.youtube.com/watch?v=v44lCcWfR0g Ray in AZ

Does the rj45 tester test the 8 wires plus the screen? i.e. all 9 conductors in stp cables?

The RJ45 connection does not test the ground. However, if you touch metal components of each RJ45 connector on the cable to the metal rings around the 1/4" testers, then the ground should tone out if it's connected.

Will this test cables with different connectors on each end? for example, a trs to xlr adapter cable with 1/4" trs on one end and xlr on the other?

Yes, you can test cables with two different type connectors at the same time.

Where (in what country) is this made?

The OSP CT-04C is manufactured in China.
