Well, I'll believe you.

But won't the reading be very dependent on the spacing of the conductors?

JOOI, did you compare it to results from a 'normal' clamp meter?

Whenever I've done similar surveys I used an IEC C13->C14 cable ("kettle extension") that's been pared-back to reveal the individual conductors, thankfully most kit had dual PSUs, so supply to one could be removed, insert my test lead, measure with clamp meter, replace and then repeat for the other PSU.

Exactly. Three years.

(See also: ARW's tales of apprentices)

I believe it was optimised for certain standard cables:

and does say it approximates with others.

It's a bit moot anyway - I noticed Megger have discontinued it due to "lack of demand" which I find not entirely believable as it was and still is the only instrument that could do this.

Some googling suggests another company stepped up and offered to make it under licence under a different name but Megger had destroyed the case moulds so it would have been too expensive to start from scratch.

That's hardly fair. On the science front we have

Brian Cox Jim Al-Khalili Helen Czerski Dara O'Brien David Spiegelhalter Ben Goldacre

All fairly regular presenters/commentators on BBC TV and/or radio. (You may have to look at BBC4 or BBC R4 to find them)

I have only recently discovered why there seems to have been this increase in real scientists (as opposed to professional presenters) on TV and radio in recent years and it seems that their research funding provided by the government is directly affected by their "public outreach". (It may have always been so but I believe the effect has recently been exaggerated).

I agree with you about engineers though. I cant immediately name one who appears regularly.

So multi-core cable has 2 or 3 cores, I've not used the term multicore for when there's less than 4 conductors. Maybe because when I've used multicore wire it's been 4, 8 or more. Looks like you have to split the cores.

But when it comes to measuring currents I'd like one of these.

and with a claim like the above wouldn't we all ;-)

Ok, I'll get my coat...

jgh

It cannot work, if they balance out flow and return. It can only measure some current if there is an imbalance and another route, but then you are reading a proportion of the current, rather than the entire current.

Dell Boy was an electrician.

Harrison Ford was a carpenter.

So was Jesus.

Which TV series/ films was he in?

He was an extra in The Life of Brian.

Life of Brian IIRC

That's presumably got a Hall effect sensor at the tip. So relies on just picking up magnetic field from the conductor of interest.

Are you getting him mixed up with his dad?

Would make no difference as it is extremely easy to find out how and still not many people can, or be bothered.
