I just unplugged the Belkin 1200 VA UPS powering my computer, and plugged it
into my Kill-o-watt meter. After the UPS quit beeping after power was restored,
the meter shows 7-11 watts being consumed by the UPS feeding the computer, which
is way less than the computer (quad core core-duo processor) uses.

Does the killowatt have a problem reading accurately with UPS units?
