I know how my clamp meter works, and chortled at the idea that one could detect which "direction" an AC current was flowing in.
However I was recently shown an energy monitor where the sensor clamps round a meter tail, and has a little arrow to detect if current is flowing out of or into the network.
Does anyone know how it can tell?
