how do you have it connected to the 220? My PDU has C19 plugs, are you using an adapter to convert C19 to 5-15 and plug the kill-a-watt into it? Pics of how you have it setup would be great. I thought the 5-15 plugs were only 110V, so I'm confused how you are plugging the normal Kill-A-Watt into your 220. thanks
C13 to Nema 5-15 > into kill-a-watt > then I have an adapter that is nema 5-15R to c14 that plugs into my PDUs. If I have time ill try to take a picture later.
