I know you had something else in mind, such as a free d/l of a small applet or other, but if for technical purpose this is probably overkill: <A HREF="http://www.triplett.com/pdf/ttt_21.pdf" target="_new">Tripplet DMM pdf</A> & <A HREF="http://www.meterdistributor.com/Triplett/21st Century Series.htm" target="_new">Tripplet Soft DMM</A>
If you have a UPS, most of the time they have accompanying software that monitors power usage. I'll keep looking for an applet to d/l and if I find one I'll post again.
