if the AC voltage is good sinusoid, there is no more need to measure harmonics current. they hold no active power.
note the tha 45-65Hz is the self-power constraints, not the spectrum analysis ability. the sampling is 1600 samples/s @ 50Hz, thus 800Hz. if one can ruleout huge voltage above 800Hz, there is no place for fraud. this is not a wideband powermetter, but with some honesty among observers and some checking about DC and HF voltage, it is much enough... this mean it won't be convincing the nay-believers who will hide their delusion in any shadow even if they make it with lies and incompetence, like theyr did for Rossi. MY already started with triphase... I expect much from thermocouples (forgetting the range of errord needed to explain null result). 2013/7/21 Alan Fletcher <a...@well.com> > > From: "Akira Shirakawa" <shirakawa.ak...@gmail.com> > > Sent: Sunday, July 21, 2013 12:04:09 PM > > > As usual the critical part will be measuring input energy. > > They will use this energy meter: > > > > http://www.farnell.com/datasheets/579510.pdf > > Range: 45 to 65Hz; > It doesn't even seem to be "broadband". > > ie No DC / LF / HF -- depending on the clamps used, most likely AC only. > >
