Someone educate me please. I've never used one of these short range indicators before, and need to know how they work. 
I have an old clunker here like the one below (Standard NO.228) that is filthy and frozen solid, and decided to have a go at restoring it. Thanks to Bob's previous posts (krv3000) I've managed to get it all apart without destroying anything (so far).
How are they used exactly? Are you supposed to pre-load the needle half way through its full range, and then zero the dial?
Also, I don't know how much pre-tension I need to put on the "clock spring" when going back together after I get everything cleaned up? What say you Bob?
