1), followed by an intermittent connections test where signals are constantly sent through the cable while you flex the connectors and apply stress (including pull) to the cable itself (fig. To test a wire or other piece of electrical equipment, you use the two probes attached to the device: Your multimeter will come with 2 wires with metal probes at the end.

Be certain to touch around the cord. Once this tool beeps, you’ll know which breaker corresponds with the outlet. But you can also get a good idea of where your wires are without such sophisticated devices. A quick reminder on the test process: A problem using multimeters to test for voltage is that they typically have high impedance, typically 10.
