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.

FUNCTION BUTTONS

NCV POWER ON/OFF BUTTON

1

Press and release the NCV Power button 1. The tester will emit a

single beep, the Power On Indicator 2 and green LED 3 in the tip
will illuminate. To power-OFF the tester, press and release the Power
On / Off button 1. The tester will emit a double beep.

NOTE: The tester will automatically power-OFF following 4
minutes of inactivity to conserve battery life.

OPERATING INSTRUCTIONS

CHECKING FOR THE PRESENCE OF AC VOLTAGE

1. Press the Power On / Off button. After performing a self-test,
a green LED3 will illuminate the tip when no voltage is
detected.

2. Prior to use, test on a known live circuit to verify tester
functionality.

3. Place tip of the tester

near AC voltage. If voltage is present,

4

the unit will emit audible beeps and the red LED3 in the tip
will illuminate.

SILENT OPERATION

To activate silent operation, power-ON by pressing and holding
the NCV Power-ON button 1 for more than 2 seconds. Power­ON in this manner each time silent operation is desired.

MAINTENANCE

BATTERY REPLACEMENT

When the battery is low, the unit will power-on with a blinking red
LED2. When this happens, the batteries must be replaced:

1. Unscrew the battery cap7and remove/recycle spent

batteries.

2. Install two new AAA batteries. Note proper polarity.

3. Screw battery cap tightly to ensure a tight seal with the O-Ring6.

CLEANING

Be sure tester is turned off and wipe with a clean, dry lint­free cloth.

Do not use abrasive cleaners or solvents.

STORAGE

Remove the batteries when not in use for a prolonged period
of time. Do not expose to high temperatures or humidity. After
a period of storage in extreme conditions exceeding the limits
mentioned in the General Specifications section, allow the tester
to return to normal operating conditions before using.

Conditions indicated: wiring correct, open ground, reverse polarity, open hot, open neutral and hot/

ground reversed.
Conditions NOT indicated: quality of ground, multiple hot wires, combinations of defects, reversal of

grounded and grounding conductors.
All appliances or equipment on the circuit being tested should be unplugged to help reduce the
possibility of erroneous readings.

STANDARD RECEPTACLES

1. Verify tester operation by testing on a known live and correctly wired receptacle.

2. Plug tester into receptacle.

3. Compare the illuminated lights on the tester to the key code printed on the tester.

4. If the tester indicates that the receptacle is not wired correctly, consult a qualified electrician.
