Hence move from R to L and you will already know what the dials to the right of it are reading.....
My point is simply that that will not happen 'automatically' - one will still have to think about the figures one has ascertained 'to the right', and work out what they mean in terms of the interpretation of the 'current' ('marginal') one. In terms of the recent photo, BAS wrote : "4. The next one has gone past 100, but not got to 200.... ", but that is far from necessarily obvious to someone (since the pointer seems to be pointing exactly to 200) unless one considers the implication of the figures ('to the right') that one has already read.Keep up, John, if you start from the right, that's what you will be doing.
The easiest way to read them correctly is to work from right to left.
- .75 (which you don't report, but it helps to get started on the progression.)
- The next one has gone past 9, but not got to 0. It has gone past 9 by .75, so your reading is going to end 9.75
- The next one has gone past 80, but not got to 90. It has gone past 80 by 9.75, so your reading is going to end 89.75
- The next one has gone past 100, but not got to 200. It has gone past 100 by 89.75, so your reading is going to end 189.75
- The next one has gone past 0000, but not got to 1000. It has gone past 0000 by 189.75, so your reading is going to end 0189.75
- The next one has gone past 10000, but not got to 20000. It has gone past 10000 by 0189.75, so your reading is going to end 10189.75
But that is the end, ignore the fractional figure, your reading is 10189.
Indeed, as everyone has said, that is the conclusion one would come to if one thought about the implication of those numbers to the right, which is the only way that one will ever be able to resolve uncertainties about a dial whose pointer appears to be pointing AT a number. As I said early on .......but that's what you do when you start from the right. The previous (from right) numbers are 89.7(5) so it must be 89.75% past a number. That number clearly cannot be 2.
It's extremely easy for us 'in the know'. However, you'll see from the post after yours that the OP read that number as "2", even though, as you say (after looking at other numbers) "that number clearly cannot be 2" - and I rather suspect that he might well have made that same mistake whether he read the numbers from left to right or from right to left.... that you CANNOT do that. If the needle in one dial is very close to a number, one MUST look at the other numbers to work out whether it is 'just over' or 'just under' (or, very rarely, 'exactly') the number it appears to be pointing at.
The pointers aren't spot on but they're not that far out.I do have a question, the middle one in my eyes has hit 200 and if I was reading this, I would have reported 200.
I very much doubt that if one only had that middle black dial ('hundreds') to look at, anyone (including us us two) would be able to be totally confident whether it should be read as 1 or 2 (particularly given that those dials are not always 'perfect').The pointers aren't spot on but they're not that far out.
As everyone has been saying, in one way or another, throughout this thread, that is obviously the logic that has to be applied. For example, early on I wrote:If it was 2 that would mean it is xx289 which is nearly 300. This cannot be right because the pointer is nowhere near 3, so it must be xx189, that is nearly 200.
However, one has to be aware of 'the audience'. You and I would not (now) need to come here to ask how to read the meter correctly. However, although it's too long ago for either of us to remember, I strongly suspect that both you and I had to look and think at least twice (probably a lot more times) when we first encountered one! For someone who is not 'used' to looking at them, it really is not necessarily at all easy or 'obvious' - and it's not helped at all by the fact that (presumably to save the small cost of 4 or 5 'idler' gears) alternate dials rotate in opposite directions!However, things become clearer if you look at the rest of the numbers. If that first digit were a 1, then the whole number would be 19804. That's nearly 20000 and if that were the case, the needle on that first dial would be close to 2, rather than very close to 1 as it actually was.
Has anyone disputed that?I very much doubt that if one only had that middle black dial ('hundreds') to look at, anyone (including us us two) would be able to be totally confident whether it should be read as 1 or 2 (particularly given that those dials are not always 'perfect').
Then why did you dispute Bas' explanation and write:As everyone has been saying, in one way or another, throughout this thread, that is obviously the logic that has to be applied. For example, early on I wrote:

Whether one reads from L to R or vice-versa, the difficulty which many people have (including the OP) arises when one of the pointers appears to be 'exactly on' one of the numbers (e.g. '2' in the middle black dial in the recent photo) - and the only way one can determine whether or not it has 'gone past' the number is by reference to what the dials to the right of it are indicating.
So what. Now we are teaching someone else.However, one has to be aware of 'the audience'. You and I would not (now) need to come here to ask how to read the meter correctly.

I didn't 'dispute' anything BAS had said. I merely pointed out that, even if one reads from right to left (as BAS had suggested), one still has to 'think about' those 'numbers to the right' and be able to work out what they mean in terms of the number of interest.Then why did you dispute Bas' explanation and write:....
I agree. I 'learned' that one off someone who does it all the time, and therefore generally only do it in response to his posts. If I 'slipped' on this occasion, and did it in a post directed at you, please accept my apologies.Plus - It is not necessary to follow posts which agree with yours with a reminder that you wrote it first.
Did that type of meter coming into being at a time when DNOs were supplying (and paying for) consumer's meters?The DNOs are not noted for caring about the customer.
My apologies - reading things and not thinking about them doesn't come naturally to me, and some people have an advantage over me in that respect.I didn't 'dispute' anything BAS had said.
