Insulation Resistance - is driving me nuts.

[se7aq]

Hello Sparkies and Sparkettes.

Carrying out a IR tests I got a reading from the upstaris light (1.1 ohms) but could not get a reading of the downstairs lights, even though all bulbs were out and switches off. I could get no other reading from the other MCB's either e,g Ring, Shower, Cooker etc etc.
Actually, I left a bulb in a bedroom upstairs would that have made a differance?

Can you help? A Kinder surprise for most sarcastic answer, but a decent answer would also be great.

Cheers

Do you mean all the results suggested dead shorts?

By switches off...do you mean MCB's or the actual switches controlling whatever...

What do you mean couldn't get a reading? As murdoch has said or >500?

You must have got a "reading" of some sort, e.g. 0.0 from whatever test meter you were using?

I used a KT35 - a Continuity and Insulation tester. Recenlty Calibrated.
As I say I got a reading from the upstairs lights but not from any other MCB.
All MCB's were off.
All light/sockets were switched off. All light bulbs out, aprt from one I accidently left in bedroom ceiling light.
It was as if I was not testing, but the upstairs lights were fine..??!!??!! No readings.

How are you carrying out the tests?

Would you like to walk us through it so we can get some idea of a) what you're doing and b) where you're going wrong?

I'm trying to cut down - but I do enjoy a good wine.
