WARNINGS AND PRECAUTIONS

WARNING: Use extreme caution when testing live electrical

circuits due to risk of injury from electric shock.

• For use on 110-125 VAC sockets only

• All appliances or equipment on the circuit being tested

should be unplugged to help avoid erroneous readings

• Not a comprehensive diagnostic instrument but a simple

instrument to detect nearly all probable common improper

wiring conditions

• Refer all indicated problems to a qualiﬁed electrician

• Will not indicate quality of ground

• Will not detect 2 hot wires in circuit

• Will not detect a combination of defects

• Will not indicate reversal of grounded and grounding

conductors

• Consult the GFCI manufacturer's installation instructions to

determine that the GFCI is installed in accordance with the

manufacturer's speciﬁcations

• Check for correct wiring of receptacle and all remotely

connected receptacles on the branch circuit

• 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.

• Activate the test button on the GFCI tester for a minimum of

6 seconds when testing the GFCI condition. An audible or

visible indication on the GFCI tester must cease when tripped

• If the tester fails to trip the GFCI, it suggests:

1) A wiring problem with a totally operable GFCI

2) Proper wiring with a faulty GFCI.

Consult with an electrician to check the condition of the

wiring and GFCI."

• CAUTION: When testing GFCIs installed in 2-wire systems

(no ground wire available), the tester may give a false

indication that the GFCI is not functioning properly. If this

occurs, recheck the operation of the GFCI using the test and

reset buttons. The GFCI button test function will demonstrate

proper operation.

Basic Instructions:

1. Unplug all appliances and equipment on the circuit being

tested for best results.

2. Plug the tester into the socket and note which indicators light.

3. Refer to the table to determine the wiring.

Before plugging the tester into a GFCI socket, trip the GFCI

socket by pressing its TEST button. The GFCI should trip. If the

GFCI does not trip the socket is faulty and should be replaced.

After the GFCI trips, press the RESET button on the socket.

Plug in the GFCI socket tester and press the Black Test button

on the tester for at least 6 seconds. LED indicator lights when

GFCI testing is in progress. The GFCI should trip, shutting off the

red and amber indicator lights. If the GFCI does not trip there is

either a problem with the wiring of the socket or the socket

itself. Consult an electrician to determine the problem.

Note: For use on 110-125 VAC sockets only. Does not indicate

the quality of the ground. Will not detect 2 hot wires in circuit,

two or more faults in combination, or reversal of grounded and

grounding connectors.
