How do you connect test leads to a circuit?
If required, press the continuity button. First insert the black test lead into the COM jack. Then insert the red lead into the VΩ jack. When finished, remove the leads in reverse order: red first, then black. With the circuit de-energized, connect the test leads across the component being tested.
What should the resistance be on a continuity tester?
Continuity tester has two leads connected to a small battery, and when you touch the leads together to complete the circuit, the meter should register 0 resistance or if you have a dedicated continuity tester, the light should come on. If you’re using a digital multimeter, the device may also beep.
Why does the light come on on a continuity tester?
This is because the resistance of conductors between the two ends is usually very small (less than 100 ohm). Continuity tester has two leads connected to a small battery, and when you touch the leads together to complete the circuit, the meter should register 0 resistance or if you have a dedicated continuity tester, the light should come on.
How is a continuity of circuit protective conductors test carried out?
If the device is a switch, the tester should go off and on when you flip the switch. You can use this technique to check appliance switches, thermostats and fuses. Be sure the power is off, then touch the leads to the terminals of the device in question. Continuity of Circuit Protective Conductors (CPC) The test is carried out as follows:
How can I Check my continuity tester?
Check the tester by putting the leads together and ensuring that the device lights up, beeps or registers 0 ohms of resistance. Touch one lead on one of the hot terminals of the device, identified by a brass screw. Place the other lead on any other terminal except the green ground terminal.
