It's really very simplistic. You loosen the jam nut, then this tool fits over the valve adjuster and you tighten all the way down, then you line up a small wheel so that the pointer is at a certain mark, then you turn the adjuster counter clockwise the the next mark - which is calculated to the precise measurement to get you to .004.
After using the tool, I measured all my valves with too feelers (the correct .004 and one size bigger - for the go/no go effect). Every valve was spot on.
Here's a thread - started by Kirk, that shows how the tool works:
