I am not an electrician, but sell some things online.. today I had a customer who just received the multimeter I sold him. I don't know anything about these. Please if you can help me help him I'd appreciate itHis question to me was:the unit is not getting the same reading when connecting to the bottom front ports.The bottom right port is functional and reading when an electrical current is present. (Picture 1)The bottom right 400 mA port is not functional, power does not get to the test device and no electrical current is shown.
