To be fair to me, i was using it to test whether the power was off, so basically using it for what it's made for. Just noticed it was giving voltage on what should be the switch live.To be fair to the OP (see post #7) he is using a Fluke voltage tester, a lot more use than a chocolate fireguard.
It's not a 'proper meter', but safer as a basic tester than a cheap multimeter!

I also accidentally called it current above - i don't know what else to call AC but it flashes up AC when voltage is detected. I figured since it's 50v AC i could call it 'AC current' since AC is alternating current. Is there some other terminology i should be using?
