Measuring Zs with all circuits connected or just the circuit being tested.

Yes, because that is the two connections that do the test. See the highlighted part in my post 26.

"My bad", as they say! Although I must have read that paragraph countless times, even before you posted it, I had never taken in that it starts with "L-PE". My apologies (to myself as well as others ). I'm still a little surprised that this is not mentioned in the initial ("L-PE") section of the instructions, it just being 'hidden' within the "Line Impedance" section.

No, you said your meter couldn't do it.

I initially did, because that's what I'd always believed was the case. More recently I've suggested that (as you were presumably implying) that by re-arranging the leads, one can do a high current "L-PE" test.

You don't reverse the leads; you just connect N to Earth. The meter doesn't know.

I was talking about 'reversing' N and E - but I agree that the N test lead doesn't need to be connected to anything.

Anyway - that's how it's done. There is no point arguing about it

As above, I've not been 'arguing' - I've merely learned something about my machine that I had never previous realised (in many years of using it and identical predecessors)!

Thanks for enlightening me!

Kind Regards, John

Now you'll be able to perform a proper manly loop impedance test where no RCDs are present.

Ive got a fluke and you can't (I don't think) do a 2 wire no trip test

I hear you can do this with the kewtech?

Correct.

I hear you can do this with the kewtech?

I wouldn't think so but if so I should be interested to know how.

 

[pete01]

 

[EFLImpudence]

Well, that's not really the same.

He's using three wires but has N & E joined together and calling that two wires.

You could do that with any meter.

I don't think you can with the fluke, can you? Never tried

I will (thanks to EFLI), and I'll be interested to discover how the results of 'proper' and no-trip measurements compare!

 

[EFLImpudence]

Yes, but he is doing it because there is no neutral - like you can do a no-trip test at a light switch by putting both N & E leads on Earth.

The Fluke high current test (that would trip the RCD) only uses L & N connections at the meter.

 

[pete01]

I've never done that, probably because my leads aren't capable of joining together

 

[EFLImpudence]

You could touch the same thing with both.

 

[pete01]

You could touch the same thing with both.

Yeah suppose I could I'll try it

 

[JohnW2]

Maybe not, but I would imagine that you would be more than capable of arranging an electrical connection between them, wouldn't you ?

You can buy a piggy back lead connector type thing, I wouldn't fancy chopping my leads to wago them lol

one can

Nor would I, but one could electrically connect the two conductors without having to chop them
