Absolutely. For the devices I measured (monitors, television, etc), I repeated a start/stop cycle a few times. The kill-a-watt does have a bit of a delay and slow sampling period, so by repeating the power cycling a few times to get your "power on surge" measurement may be a good idea (from a "how much power does this really use" POV, not a "good for hardware" one ;)).
As an example, some new servers we built have a poiwer-on consumption of 4-5amps @ 120volt, but settles to just a hair over 2amps after a few minutes (although this was measured on a metered PDU, not the kill-a-watt). > > Andy > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "NLUG" group.
