Got my first advanced timing light, need tips

I might add, the knob in the timing light makes it so you can find your advance while constantly having the timing mark hit "0". So if the knob is at say 12 and the mark is hitting zero, you're at 12 deg BTDC. Turn the knob at a given rpm til the mark hits zero and that is where your timing is. Set the knob to a degree you'd like to be at and see where the mark falls to know which way to turn the distributer. Just play around with it some.
