Yesterday's epsisode of Midsomer Murders failed as usual...
I had a Current Cost IAM (Individual Appliance Monitor) on the box and was graphing the energy consumption on a PC using some graph software via a ENVI display unit.
In standby the IAM showed the box using 8 watts (they are not very accurate, figure should be 1 or less) then at 15:45 this went up to 40 watts until 17:45 when it returned to 8 watts.
Later of course when I checked the box I got the usual "Failed, Unknown Reason" and wasted some more electricity...

Automan.
The reason your consumption meter is inaccurate is mainly because they no concept of power factor only using a current measurement and voltage measurement (if you are lucky)
The box is powered and waiting for a event change that never arrives. Send ITV the bill

Indeed, Current Cost say the next generation "IAM" will also measure power factor.
Why they did not include it in the first version I will never know...
When my Panasonic 46" Plasma is switched off a IAM reports it is using over 25 watts

It's not easy to measure the phase angle between voltage and current. Even the fancy ones that the power companies provide only have a clip on Ammeter. However given enough patience and an accurate stopwatch you can time the revolutions of your meter disc to get a very accurate reading of power.
Midsomer Murders failed for me today, the first time since my last post. Fortunately we were there so a few seconds into the programme I pressed 'record'. Went off to prepare the veg for dinner & returned to watch it from hd. There was 41 seconds of MMs, called David Dickinsons Real Deal. I told you the box was out to get me!!!:eek:

True, but these are plug-in modules moulded into a 13amp plug and thus volts, amps and power factor of attached load should be easy.

Workaround
1 Set each one as one off event and manually edit the start and end times to add padding (disables AR).
or
2 Enable auto padding which lets series record continue but disables AR but affects all recordings.
Thirdly compose a snotty e-mail to ITV telling them to stop B******ing about with the event id's.
I don't watch Midsomer just set the recording to find out what's going on.
Anyway Meridian recording "Failed - Reason Unknown" but the manual recording on my Mother's one worked ok so she is happy.
Cut in half Frost episodes also used to fail a lot so perhaps they had the same kind of ITV data error.

But all they have done is as you say put a clamp amp meter in a plastic box.
I would be interested to know if the ones EDF offer with their Eco Manager are any better?
I have some of these

And they can read the load of a device to within a fraction of a watt.
