[QUOTE="Haunz, post: 7167284, member: 576010"] A cheap clamp meter like the one in question uses a primary and secondary wire wound around the clamp jaws to measure the current of an AC wave.. it is calibrated as the OP mentions displaying .707 the peak value of a sinusoidal wave (at 60hz)... A real clamp meter will use a hall effect sensor, and will measure DC and any AC or pulse waveform as true RMS... Plan on spending at least a couple hundred bucks for a decent clamp.... [/QUOTE]
