Yes, this. I have 3 different model Fluke clamp meters and 2 clamp probes that all agree within 10A at 1000A (ie - 1%). We also have 4 other different brand clamp meters and not a single one agrees with the others, much less the Flukes, and are off anywhere from 30A, at best, to 100A typical (and invariably they read low, which is especially bad in my opinion). And for mV accuracy don't even think about a clamp meter... Voltage readings on them are more or less an afterthought, even for the Flukes. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/AC-DC-amp-meter-tp4665328p4665338.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
