VPI Scout setup after watching Frefmer's video

I understand all the concepts, however one question still bugs me. When I read VPI's manual they go through the set up process pretty well with one of the first things you do is set the anti skate. Here is what I don't get, if the anti skate is hooked up how are you suppose to set tracking force and azimuth correctly if ther is a constant counter force acting on it? Even if you disconnect the Lemo it still imparts a force just hanging there.

I'm a newbie at TT's so maybe I'm missing something.
