I want to use a scope to check out a circuit that is connected to
the phone line tip & ring (a plain old USA analog home phone line).
A continuity check shows that the scope probe ground clip is tied
to the green-wire ground pin of the power chord.
Am I right in thinking that I need to float the scope for this (ie. power
the scope with a 2-wire extension chord)?
