    in reply to: PZEM-051 question #20531

    Hello Ken Sowards,
    As what we said previously, we are sorry the shunt can’t be hooked to the positive terminal. That will cause that the meter”-” is connected directly to the power supply”-“. Meter may be burned.
    Or did you have different idea? would you please share us how do you going to hooked it up? It would be appreciated if you can draw a simple diagram.
    Best regards.

    Hello Ken Sowards，
    If you connect the shunt on the positive terminal, the meter”-” will be connect directly to the power supply”-“. Is it right? In that case, it is likely to burn the meter.
    Bet regards.
