I have just gone self employed as a mobile mechanic and I am currently broke! I do however NEED a scope, catch 22 I havent got the money to buy one, but cant earn the money without one! I know how to use a scope for what I need to do with it, but do not understand the technical jargon. In simple terms will the ADC-40 scope surfice to get me off the ground? Basicly I need it primerally to plot patterns mostly between 5 and 15 volts on a timebase from 5ms up to a second. Also would an accidental spike up to 200volts from a faulty unit damage the equipment beyond repair?
