Default Kill-o-watt meter used on computer UPS - bad readings?

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?


The reading seems strange (typically one would expect it to show a
higher than true figure), but cheap power meters often have difficulty
with anything other than appliances that behave like resistive loads.
Neither the UPS itself nor the PC is likely to do so.
