With the MFE PDV03 phase meter, you can quickly and easy determine the phase of the connections in a socket.
It remains a crucial question for many audio enthusiasts: ‘what is the phase’? Plugging in ‘the wrong way round’ can lead to audible interference or annoying ground loops. That is where the MFE PDV03 phase meter comes in handy. A nice detail of this one is, that you can (temporarily) place the meter between source (i.e. wall socket) and consumer. The PDV03 also has its own power outlet. By measuring 200 times per second, the phasemeter is able to determine whether the connected device is correctly ‘phased’. The MFE PDV03 costs €398.
