  1. concerning REPLY#26 I believe you will need a power supply which is isolated from the voltage which you are measuring for the panel meter to work (ie:the power source should be a 9v battery per manufacturer). This is causing me problems as I have 25 students encountering this problem (we added a panel meter to their project this year). Does anyone have any suggestions/ alternatives to the 9v battery other than adding a transformer. thanks
