I've never measured cold. I can't help ya with that.

Get it warmed-up and see what reading you get. I'm typically around 3.7, fully warmed.

It really shouldn't matter which side of the manometer you hook to; one should read positive, one should read negative. You'll probably want to put a hose on the other nipple as well, though, and route it somewhere where it's protected from any wind or venting. It'll be very sensitive.

I assume you watched the video that JFP linked you to earlier?
