make certain the meter has 20k impedance. i'm no ee but was told never use an analog meter, only digital when dealing with ecus. analogs allow to much voltage into the circuit. good digitals have 10k built into them and prevent that.

yes, a dvom should be fast enough so show the signal swing. all i had before i got scopes. good luck, chuck.
