The power meter came in today. It took just about 2 weeks from England.
It was packed well and in good shape. Easy to install. Harder to calibrate.
8 pulses on the house meter every 60 seconds= 480 Wh.
Setting the AC to 240 volts (in the setup menu) got me close very to 480W.
Right now, the Sanyo is drifting between 470 & 490 watts for a while, then
dropping down to 30 watts for a while and then kicking back up to 480 again.
The calibration might be a tad off, because it's hard to watch two displays
while counting dots.. Needed to watch the 480 watts, to make sure it didn't
drop to 30 for half my 60 second count.. I did the count and checked it
against the meter about a dozen times before I was happy with the setting.
I've got the transmitter set for it's fastest transmit rate (every 6 seconds),
so I can see all the little ups & downs..
After it runs for a day or two, it should give more accurate predictions
of the daily average kWh & cost etc.
I'll start posting the data soon. It looks like the temperatures are going
down into the 20s and teens as December kicks in..
Edit:
In case anyone is interested in one of these Elite units, they are about $80 shipped
and take 1 to 2 weeks to get here from the UK. Mine took two weeks.
