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.

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.
3
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). 3.Replace battery door and fasten securely with screw. WARNINGS: To avoid risk of electric shock, unplug from any voltage source before removing battery door. WARNINGS: To avoid risk of electric shock, do not operate tester while battery door is removed.
