Default Snap-On Dwell Tach

I was given a Snap-On Dwell Tach Model # MT-715 the other day. I was wondering if anyone knows where I can find instructions for it. I Googled it with no love.

Connecting it is pretty straight forward, I am just wondering about the knob on the far right, specifically the "Set" setting? It doesn't have any hard detents, more like a potentiometer. Thanks.

I'm told the dwell angle for a Model A distributor is 42°.
