Champion plug scope

I just picked up this scope at a flea market. Does anyone have an idea of where I could get an instruction manual? It has a little bit of instruction on the side.

It must work like the old SUN machines. A clip for the coil wire, a clip for No. 1, a clip on the neg coil wire. High spikes indicate high voltage needed to fire, bad wire, bad plug. Low spikes are cyls that have lower compression. I still use old sun machines on Marine 4 cycle inboards every day.

Not sure but the company has a cool sign.
