1.General Specifications
•
The instrument is an electrical outlet tester that tests the wiring condition at an electrical outlet, and inspects
GFCI and AFCI devices.
• It is designed for use with North American 120V electrical outlets.
2.Safety
WARNINGS: To ensure safe operation and service of the tester, follow these instructions, failure to observe
these warnings can result in severe injury or death.
• The instrument is designed for use with North American 120V electrical outlets, do not connect to higher voltage
electrical supplies.
• Prior to use, always verify tester operation by testing on a known live and correctly wired electrical outlet.
• Do not attempt an AFCI testing event on a circuit with powered ON equipment or devices, remove or power OFF
prior to testing.
• Do not use if the tester appears damaged in any way.
• The tester is intended for indoor use only.
• Other equipment or devices attached to the circuit being tested could interfere with the tester, clear the circuit
before testing.
• This tester only detects common wiring problems, always consult a qualified electrician to resolve wiring problems.
• Do not attempt AFCI, GFCI or 30mA ground fault testing on an incorrectly wired outlet, consult a qualified electrician
to resolve wiring problems.

5.Operating Instructions
5-1.Power ON/OFF
• Press the Power Button to power ON/OFF the tester.
• When the tester is powered ON, the Power ON indicator will be illuminated.
• The tester will automatically power OFF after 2 minutes of inactivity to conserve battery life.
Note: Always power ON the tester before inserting the plug into an electrical outlet.
5-2.Wiring Condition
• Prior to use, always verify tester operation by testing on a known live and correctly wired electrical outlet.
• With the tester powered ON and inserted into the outlet, the wiring condition will be indicated by the wiring
condition indicators.
• If the outlet is energized, the Hazardous Voltage Warning and the Energized Indicator will be illuminated.
• If the tester indicates that the outlet is not wired correctly, consult a qualified electrician.
• The wiring condition will be communicated as detailed in the table below.
Indicator illuminated Indicator not illuminated Indicator blinking
Note: Conditions not indicated include, but are not limited to, quality of ground, multiple hot wires, reversal of neutral
and ground conductors, and combinations of defects other than dual open neutral and ground.
Note: All appliances or equipment on the circuit being tested should be unplugged to help reduce the possibility of
erroneous readings.
5-3.GFCI, AFCI and 30mA Ground Fault Functions
Note: Check the GFCI, AFCI or 30mA Ground Fault devices’ user manual for information on how the specific device
operates prior to using this tester.
1.Power ON the tester and insert the plug into the outlet on the circuit under test, noting the wiring condition.
2.The Wiring Condition indicator should indicate Correctly Wired, the Hazardous Voltage Warning indicator should be
illuminated, and the circuit status indicator should indicate Energized.
Note: If the tester indicates that the outlet is not wired correctly, do not attempt to initiate an electrical testing
event, consult a qualified electrician.
3.Press the GFCI Button, AFCI Button or the 30mA Ground Fault Button to initiate the relevant electrical fault
event.
4.If the Not Energized indicator is illuminated and the Hazardous Voltage Warning indicator is not illuminated, reset
the GFCI, AFCI or 30mA Ground Fault device by pressing its reset button.
5.After reset, the Hazardous Voltage Warning should illuminate, the wiring condition should indicate Correctly Wired
and the circuit status should indicate Energized, the device appears to be functioning correctly.
6.If the circuit remains Energized, or any other condition is indicated other than Not Energized, the device being
tested may be miswired, may not be installed correctly, or may not be functioning appropriately, consult a qualified
electrician.
Note: The AFCI button will be deactivated if the tester detects that the electrical outlet is not wired correctly.
Note: Allow 20 seconds between successive AFCI testing events.
Note: If the AFCI indicator is blinking following an AFCI testing event, a successive AFCI test cannot be initiated,
wait for indicator to turn OFF prior to attempting the next AFCI testing event.
6.Maintenance
6-1.Battery Replacement
When the Power On/Low Battery Indicator indicator is blinking, the batteries must be replaced.
1.Loosen screw from battery door.
2.Replace 3 x AAA batteries (Note proper polarity).
