Is my meter running fast?

[endecotp]

The numbers only go up per kWh unfortunately

Don't believe you. I reckon there are two digits after the decimal point.

I would have guessed one digit after the decimal point.

I wonder who is correct?

As I said, I was certainly surprised.

bellissimo: could you possibly provide us with a clear close-up photo of just the meter?

Kind Regards, John

Well you may reckon that, but it wont change the fact that there isn't. Photo proof below:

That was quick. I was about to propose a wager on the outcome.

I was riled into action by endecotp's questioning of my integrity

 

[endecotp]

On the ones that I have seen, there are two fractional digits at the right of the display where yours has a blank space.

Very peculiar.

 

[ekmdgrf]

Mine has a single decimal but then it's one of the olde skoole mechanical ones.

 

[bellissimo]

I think they can be programmed to show 'up to' two decimal places. This one obviously was programmed to show none.

To add to the confusion, it describes itself as a 'Watt Hour Meter" (not a "kWh meter"), but I cannot believe that a display with only 5 digits is in Watt-hours!

I wonder if it can be configured to display different resolutions?

Probably, but I suspect you need some special tools and some inside knowledge.

I guess the watt hours refers to the fact that it does flash for every watt, so that is the finest level of granularity.

We have the same meter. Only integers I'm afraid.

Well I turned the power off overnight for 8 hours, and the meter ticked over 2 kWh (it has just ticked over before I went to bed, so this is a minimum increase), as suspected based on counting the watt flashes.

I don't think there is much more I can do now. I phoned Scottish Power and they tried to claim that this was normal, and even after you turn off the power then some residual energy can still go through the meter. This may be true, but a residual 2 kW seems excessive!

They have agreed that they will send someone out to install a check meter, but as there are still unresolved disputes on my account due to several previous cockups from them after I switched, then this will probably not happen for several months...

2 kWh over 8 hours is an average of 250 watts load.

If the main switch was OFF and everything was isolated by that main switch then there is a "problem" with the meter.

There will be small trickle of current through the capacitive effect between the meter tails and the internal construction of the main switch. But that is at most a few hundred milliwatts ( less than 1 watt ) with long and closely bundled tails..
