I recently acquired another 'teener. See video here.

I have a leakdown tester like the one pictured below. The included instructions are pretty worthless. There is a hose extension that screws into the spark plug hole in the head. The other end connects to the gauge. My question is, do I add air from my compressor and use the regulator on the tool to set the leakdown gauge (on the right) to 0% and then connect it to the piece of hose, or do I assembly everything together and then add air?

I tried the latter method and used the regulator to adjust the leakdown gauge to 0% and then it never went down.
