Continuity Testing
- Before taking a continuity test, make sure that power to the device or circuit under test is disconnected and that all fuses are removed.
- Touch the probe to one end of the conductor to be tested.
- Place finger or hand on the metal plate located on the tester handle.
- Use other hand to complete the circuit on the other end of the conductor.
