Hi there this is my 1st post so I will introduce myself, I am an electrician in Australia, I want to make a unit that I can leave at a clients premises that will log power volts and current.
-
I have purchased a 9v AC transformer we have a 240v nominal voltage here and my RMS voltage at my home is normally around 245v. How do I calibrate the volt reading to suit my transformer and local voltage to workout an accurate power value?

I want to use the pulse counter to compare what the network operator’s meter is reading and what the open energy meter is reading (Some of my clients don’t trust the network operator and want a independent meter to test the consumer meter)
