So I ordered a new tool for the tool box, and received it in the mail today.
And the tool of the day is: a Vellman HPS10SE O-scope

Now how exactly do I go about using it? (altough it has an auto fucntion)
I'm pretty much going to be using it to set gains at work and at home on my own projects.
I have all the test tones one could need thanks to AutoSound 2000.

Basically I need to know how I hook it up to the amp to measure the wave and what should I be using as a load?
I've heard/seen of resistors (dummy loads) or reactive loads (speakers).
I would assume that using the reactive loads would be better, but I have been known to be wrong before.

There is a centre pin and wire with an alligator clip on the end, what do I do with them?

Pics would help me out HUGE (I learn to see it done) reading owns me. I think I have mild dyslexia.
