The RadioShack 22-801 is probably the most user friendly meter I have ever used. It's hard to imagine anyone that couldn't understand it....heck, even my mom used it to check batteries!

Does that meter have any CAT ratings for connecting to mains outlets, some meters like this, I've heard have exploded when connected to full voltage.
It is not the actual mains voltage that causes this, it is transient voltages that will destroy a meter.
