sounds easy enough!!  thanks! hope multimeters aren't expensive 

Depends on what type you get.  I think Gavin's definately on the right track for getting an analogue one for EM's.  They are cheaper.

I've had a couple of digital ones....A real cheap one from Bunnings...No good.  Then a cheapish one from Jaycar which I thought was OK, but has been giving misreadings the whole time.  I finished up with a Fluke, which are a very good multimeter.  Although I'm using mine more and more so the cost wasn't too bad.
