Which setting to use to measure exact voltage with this multimeter?
I purchased this multi-meter from from iFixIt: Digital Multimeter and I want to measure voltage in my wall outlets in the USA.
1) Which setting should I use on this multimeter to measure exact voltage in US Based outlets? I don't want to choose the wrong setting and burn the multimeter.
2) Which setting should I use to measure exact voltage in European (220V) outlets?
My goal is to get exact reading of the voltage level coming out of outlets in my home.
