Outlet Circuit Tester Operation:
1. Plug the tester into any 120 Volt standard or GFCI outlet.
2. Only a single LED should illuminate
3. The text adjacent to the lit LED will indicated the wiring condition.
4. If no LED illuminates then the hot is open
5. If the tester indicates a wiring problem then turn off all power to the outlet and repair wiring.
6. Restore power to the outlet and repeat steps.
NOTICE:
1. All appliances or equipment on the circuit being tested should be unplugged to help avoid erroneous readings.
2. Not a comprehensive diagnostic instrument but a simple instrument to detect nearly all probable common improper
wiring conditions.
3. Refer all indicated problems to a qualified electrician.
4. Will not detect two hot wires in a circuit.
5. Will not detect a combination of defects.
6. Will not indicate a reversal of grounded and grounding conductors.
TO TEST GFCI PROTECTED OUTLETS:
1. To test GFCI (Ground Fault Circuit Interrupter) protected circuits plug tester into GFCI protected outlet. Verify the
power is on and that the outlet is wired properly.
2. Press the GFCI test button.
3. If circuit is wired properly the main GFCI outlet should trip and power to the circuit will be cut off (this is indicated by
the LED lights on the tester going off).
NOTICE:
1. Consult the GFCI manufacturer's installation instructions to determine that the GFCI is installed in accordance with the
manufacturer's specifications.
2. Check for correct wiring of receptacle and all remotely connected receptacles on the branch circuit.
3. Operate the test button on the GFCI installed in the circuit. The GFCI must trip. If it does not — do not use the circuit
— consult an electrician. If the GFCI does trip, reset the GFCI. Then, insert the GFCI tester into the receptacle to be
tested.
