The negative pin of power supply and the negative pin of signal input on the circuit of panel meter have already been connected. So it is highly recommended to use an isolated power supply or be very carefully about the position of this panel meter to avoid short-circuit.
If an AC ammeter and an AC voltmeter are used at the same time, their power supply must be well isolated.
Mail us if you don't know the correct way to connect the panel meter!!!
