ATC Installation part 3

At 0.48 timestamp you say biggest number, the numbers are negative.... you want the smallest number (Mr. Literal here). Also, if you can get a helper to do this with it sure helps a LOT. Seeing or feeling a small deflection 4 feet away is tough. A jog wheel also makes it easier ... on click on the wheel was about a 0.01" movement at x100.
