Just quickly do the best you can by eye then fine tune it by feel when the bike is on on its shakedown ride. If you can't do that you have no business messing with tools.
That's fine if it's your bike and you know how to readjust it during or after the first ride. It's more of a problem if it's a customer's or friends bike and they are the ones who have "no business messing with tools." Then you really want to get it right the first time.
