Hi, I bought EV-ADE9153ASHIELDZ and tried to measure voltage and current. When I connect voltage 120V and A channel to current transformer, I saw 125V and several A current without any load. I tried to calibrate with button. After that, I could read near 0V. I tried to cal with and without volatage/current. Still same. Can you help me how to debug or make it work? Best regards, Philip
