Just a note. Sometime back there was someone selling new proof meters. He noted in his add that they were not accurate and would give a false, faster or slower reading. Not sure which. However they would look good as a temporary or for a quick restoration. They were only selling for, I believe $8.00. Not bad if just for show.
Don't know if this has anything to do with what this guy was seeing or not.
