Please note that I had given a separate power supply (battery) to opmap and this was not in anway connected to the AC mains I was measuring,since normally DVM uses battery. I had not connected the neg of batt supply to common of AC line for common ground. This makes the situation even more strange!!! Could you publish your circuit here? Kai |
