Default Ampy Electric Meter, What Do The Lights Mean?

Hi All,

We live in a rental property, and i was reading the electric meter the other day, and noticed that mine had a solid red light on, 2 others had flashinig red lights, and the others had no lights on them. They are all the same meters, AMPY single phase. They look like these ones, http://cgi.ebay.co.uk/ws/eBayISAPI.d...ksid=p3907.m29

The right hand light of the two is on with my meter.

i was wondering if anyone knows what these 2 lights mean in thier different states? or who i can ask?

The meters say southern electric on them, but im on scotish power now.

Above the light (LED) does it not say 1000 imp / kWh? This means that it should flash for each Watt consumed.

The right hand light of the two is on with my meter.

The left hand light is not a light but a sensor (optical port)

If it's off, no electricity being used or very little.
If it's flashing, each flash is one Watt i.e. 1000 flashes = one kWh or one unit.
If it's on continuously ??? Is it always on continuously? It may be faulty. Are the digits incrementing fast?

No its not always on, it seems to be on when i leave for work, but off when i get home.

The digits are going fast, 2 units yesterday, normally 20ish a week so far.

Twenty units per week is quite low consumption i.e. just over 1000 per annum, when the average is over 3000.

You say it's flashing when you leave for work - do you have storage heaters? If so it would be the energy they are consuming that is causing the flash. Also I know from my house that the morning is when everything is on - kettle, lights, shower, tv etc

The red light on these meters is the equivalent of the old 'spinning wheel', the more electricity being consumed the quicker it flashes....have a look at it the next time you stick the kettle on, bet it flashes quicker then!

If its on solid red then it could be that you caught it whilst it's on a flash, but as you use such a small amount of lekkie it will take a while to go off again. it could also mean that it has been wired up wrong...highly unlikley as the meter is showing an increase in consumption.

no, havent got storage heaters.

the lights on for at least 30 seconds while i stand there, obviosuly i havent watched it all day, but i have seen it lit up for a while a few times.

Ive seen it flash before too, and the other 7 meters seem to just be flashing now and again.

isnt there user guides for these things or anything?

It doesn't work like that as Mark Benton would say! A flash is a flash e.g. one impulse or flash = one unit.

One flash (or impulse) does not equal one unit, if it did we'd all need to be big earners to afford lekkie; the number of flashes per unit should be written on the meter. The meters I fit have 1000 impulses per KW(unit), a second LED gives a longer impulse once per unit.

On initial fit he LED remains constantly on with no load on the meter, once the power is switched on to the house and a load is present the meters led's will 'flash' or recieve an impulse.

That depends on your definition of one unit. These meters register units of one watt and flash once for each watt used. As already stated in post #2, 1000 flashes equates to 1kWh or one chargeable unit of electricity e.g. a cost of approx 10p.

One unit of elec is a little bit more than 10p - or will be when all the prices have gone up!! It's like 25p at tier 1 for me.

Perhaps, but if you have multiple tiers that means you're on a No Standing Charge tariff. All it means is they recoup the standing charge by making the first few units you use each month really expensive. Unless you're very frugal you're going to use most of your electricity on Tier 2, which is about 10p/unit.

By the way just to correct upthread, 1000imp/KWh means one flash per watt-hour, not per watt. A watt-hour is one watt drawn for one hour, roughly equivalent to running a torch bulb for an hour. A watt is a unit of power not energy - a kettle is 2200 watts but how much energy it uses depends on how long you boil it.

dunloadin, does this mean that there is no load on the meter when im looking at it? i guess its possible, we turn everything off in the flat when i go to work and thats generally when i look?

tho the freezer and heating timer and boiler still have a tiny bit of electric going into them i guess.

Trune, the meter records the load your house is using, and in all likeleyhood it just happened to go off load when the light was on. It's no big deal if this happens, just wish I could use as small an amount of lekkiie as you do!

Hi
I have just had a similar meter installed. Your meter is Economy 7, you are charges at one rate for day use and another (cheaper) rate from midnight to o7:00. The solid red light indicates that you are on the "night" rate.

Default Ampy Electric Meter, What Do The Lights Mean?

The solid LED simply means that there is no load on the meter (no electricity is being used) and the meter has entered 'anti creep' mode. When it is flashing, the flashing rate is proportional to the electricity being used.
