Here,s exactly whats going on, sorry I didn't have my meter with me earlier so I was being vague. Using a Sperry DSA-500 combination volt-ammeter I've gotten gotten readings at the grounding conductor at the water meter, of close to an amp. I said volts earlier, sorry, even in my own house (50 yrs. old) I'm getting .32 when I have the meter clamped around the conductor. I have the meter set on the 40 amp AC setting. This meter is only 6 months old and seems like a fairly decent tool. Thanks
