200 - >200 - 299 - 500

What do you put down as an infinite result on the insulation resistance test???

 

[uksparks]

I just put what the meter says....

An 8 on its side.

Next question.

 

[Leesparkykent]

same as uksparks, depends what make MFT you are using.

 

[uksparks]

It's never infinite anyway... It's always going to have s limit so you should put what it says on the screen in your meter, if it says 168M you put that.

 

[telectrix]

An 8 on its side.

Next question.

both my analogue megger IR testers have this miraculous "8 on the side". it the needle says it, that's what it is.

I tried that but I can't type with my laptop at 90 degrees.

My AVO doesn't!

That'll be FSD then

 

[Guest125]

See, I am glad I asked. I am putting a 70 page EICR on to the NICEIC on-line certs and I was putting 200, 200, 200, 200, 200, 200 etc... But I noticed the guy doing the test wrote 299. Then I thought - why the difference?

I have always input 200 and never really knew why.

other way round. fsd is zero Meg.

OK smart arse, different Infinities there, is there?
Which, as you clearly know, there are!

 

[telectrix]

My metrel MFT comes up >999

Shows how long since I last used mine! :smilielol5:

just does the bang test lol

 

[uksparks]

What voltage setting is it on though?

on my fluke 1654b I put it on 500v and then it limits it, one min we are not talking IR are we?

are talking continuity?

 

[telectrix]

we are talking IR, or at least i hope so or my previous posts are pants.

 

[Pete999]

What ever the MFT says is what goes on the test sheet

 

[Guest125]

we are talking IR, or at least i hope so or my previous posts are pants.

Does it really matter if we are talking about IR or not???? All your posts are pants....:ihih:

 

[uksparks]

Yeah so on my fluke, if it's set to 500v it only goes up to >500 or 250v says >250 and so on, it doesn't say 2000

 

[Leesparkykent]

IR at 500v

Can you send me a small picture frame so I can print that out and frame it?

 

[Marvo]

I tried that but I can't type with my laptop at 90 degrees.

If you're using a windoze device you should be able to open a run box and type in 'charmap' (without the ' marks) and you can copy the symbols from there and paste them into a document or even into the forum reply box.

If you're using a Crapple device you'll probably need to pay extra for the character map license and you'll probably only be able to copy the symbols via your itunes account which will add DRM and probably charge you extra for it as well.

 

[Guest125]

Can I just say that I did not actually try my laptop at 90 degrees....

Just saying!

 

[telectrix]

you'd be hard pressed to get it to 90degrees in this weather. it's bloody freezing. also if you did, your fingers would blister and your mouth dry up ( wishful thinking there :juggle2

 

[Adam W]

The meter might say 'over-range' but I don't accept that as true 'infinity'. If the range of the meter was 500MΩ and it came up with 'OR' or even if it said '∞', I'd reference the range, eg '>500MΩ'

 

[D Skelton]

No such thing as an infinite IR reading, it's physically impossible. Resistance is finite.

>299Mohms just means that there is more than 299,000,000ohms of resistance between the two conductors. 299,000,001 is more than 299,000,000, as is 1,000,000,000,000,000,000,000,000,000. Don't mean it's infinite though.

Don't worry, to the layman, the nature of infinity isn't an easy one to grasp

If the meter says >299, put >299 down on the SOTR.

 

[Engineer54]

I'm gobsmacked that any electrician would need to ask the question in the first place!!

With the forum hive mind, shouldn't it be 'Resistance is futile'?

And if the meter says infinity? Bearing in mind that on an analogue scale infinity is a theoretically valid point

Although I doubt that anyone who is struggling to read/understand a digital meter correctly will ever have a hope in hell of reading an analogue one.

 

[D Skelton]

And if the meter says infinity?

Buy a new meter, coz the one you're measuring with is wrong, which means it's a load of cack lol.

Really. You are gobsmacked? You must have some great life experiences if this question leaves you "gobsmacked".

 

[Anthony S]

No such thing, the meaning of infinite is endless, in other words you can not put a figure on it.

If any of us doing our 2360's in the 80's mentioned the word in relation to a test result, we got a b@ll@cking.

you knew what I meant!!!

But if anyone's looking in they might think its for real lol

I remember sparks who would use the word socket for a metal conduit coupler ?

Or when people say spur instead of fused connection unit...

Well, ....it seems like at least 4 others here have exactly the same thoughts as me!! lol!!

 

[Guest125]

I do not think the question was gobsmacking though. It was only a question.
