Is this a 240V or 120V Circuit?

The voltage I read was jumping all over the place.... my DVOM is a harbor freight cheapie and I don't particularly trust it. Could a low battery be causing a fluctuating reading?

I'm going to buy a new, higher quality DVOM today. Time to get serious on this. Sorry I'm such a newbie on AC circuits.

It is quite normal for the readings on cheaper digital meters to vary !
And for the average home handy man it doesn't really matter that much.
But if you want a better quality meter go for it !
