Mitch provides an overview of ghost or phantom voltages and how they can impact electrical testing and troubleshooting. He demonstrates ghost voltage using a non-touch tester, solenoid tester, and digital multimeter.
Mitch uses a Fluke 117 and Klein mm1000 to demonstrate the features and limitations of using the tone setting on a multimeter.
