What kind of a voltage meter can I use to monitor what voltage is coming in the power outlet and most importantly how many hz it is.
So is it really 110v at 60 hz. I am testing some invertors and want to make sure that eveything is kosher before I plug in something. Also what would help is if I could monitor 220v at 50 hz.
thanks & regards,
