K3 #642 measures just over 4mA when off. FT-847 reads 12mA. However,
with both those loads on the FP-1030A power supply, it appears to be
consuming about 3wH [72 watt-days/26.28 kw-years], apparently just to
light the little LED on the panel. In fact, it's very close to 3wH with
all the loads disconnected. Our highest marginal PG&E rate is $0.34/kWh
which works out to $8.94/yr max.
Maybe a "leak" outside the K3(s)?
It does raise the question, just how many electrons are being wasted in
the TV, DirecTV receiver/DVR, microwave, and the myriad of phone/Kindle
chargers plugged in all over the house, not to mention this computer
which is on nearly all the time? I suspect it's a lot more than 9 bucks
a year.

Nope. I measured both units several times, and just now repeated the
measurements.

Hi Jim - you must be misreading the meter by several decimal points :-)
We just measured several K3s in the lab and they both draw less than 5
mA when off.
