How do you test if a circuit is live with a multimeter?
How to Test for Continuity with a Digital Multimeter
- First insert the black test lead into the COM jack.
- Then insert the red lead into the VΩ jack.
- With the circuit de-energized, connect the test leads across the component being tested.
- The digital multimeter (DMM) beeps if a complete path (continuity) is detected.
