200 - >200 - 299 - 500

Do modern analogue meters have the infinity symbol on them?

I haven't seen a modern analogue one so wouldn't know. But if using one and it reached the end of its scale I would read the scale upwards and write down the maximum figure that it goes too and not infinity.

Not arguing, just a good debate to have on a Friday I have seen someone assume the figures shown of 200/999 etc. are absolute values of the circuit being tested - they didn't realise that the tester was actually 'maxing out'. Daz

Heres a example, this meter has the infinity symbol on it, yet the MI says it only reads up to 100 Meg ohm.

I do remember having a nice Robin analogue I/R & Cont tester , and that had a small infinity symbol on the end of the scale , nice meter until someone decided to relieve me of all my tools on the van ..

If an analogue meter swings over to infinity, the reading is not infinity. Daz

So you write down the highest numeral

I've got a Robin analogue I don't use it but the highest reading is 100 then a line what I reckon represents 200 then the dreaded 8 on its side.

Which model robin is it? What does it say it reads up to in the MI?

If we're going to be strictly mathematically purist here, I think that saying "infinity" is a lie, as it will be measuring a value, however large, it will still exist as a value.

what they could put is a little arrow diagonally pointing upwards from ledt to right and then the infinity symbol, which if memory serves correctly means "tending to"

by the way I have only read last few posts not whole thread so if I am repeating someone or speaking cobblers then I apolgise, return your tankard, and bid you good day.

Its 3111V model and reads up to 100

Again the MI says it reads up to 200 Meg ohms, not infinity. I imagine the infinity symbol is just to indicate the tester can not read beyond the scale it is showing.

Ive read it all now and see my point has already been made. Sorry for filling this thread with unnecessary monotonous duplicitous detritis.

I especially enjoyed Damians expletive post it made me chortle.

The Megger 1552 shows >299
The Megger 1720 shows >999
The Megger 1835 shows >999

As I use the 1552, I put down what it says.....>299
Unless of course it says less than this, then I would put the actual reading it says.

I see what you're saying, but the 200 is showing because the meter has reached the top of it's reading capability. The actual reading is above this. Of course, there is a slim chance that the circuit resistance could actually be bang on 200M ! Daz

So you would put ≥200

 

[Guest125]

Seems as there are many different ways that everyone does it. Interesting.

The 200 mark must be the line indicator with no numeral marking as mentioned in my post 66

Strange why they didn't engrave a 200 there ?

Old meter mate, I picked it up 20 years ago.
