WARNINGS

To ensure safe operation and service of the meter, follow these
instructions. Failure to observe these warnings can result in
severe injury or death.

• Failure to follow instructions could result in death or serious injury.

• Prior to use, always verify tester operation by testing on a known live
and correctly wired electrical outlet.

• DO NOT use if the tester appears damaged in any way.

• The tester is intended for indoor use only.

• The tester is designed for use with 120V AC electrical systems. DO
NOT connect to higher voltage electrical supplies.

• 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.

• If using accessories to connect to bare wires ensure that the circuit
is not energized before inspecting, applying, or removing the
transmitter.

• Exercise extreme caution around energized, bare wires, especially
when working in or around an open breaker panel.

OPERATING INSTRUCTIONS

FINDING CIRCUIT BREAKERS

Insert the transmitter 1 into the electrical outlet and note the Wiring
Condition 6 & 7. If the transmitter indicates that the outlet is
energized and correctly wired, prepare to scan the breakers in the
breaker panel with the receiver 2.

If the tester indicates that the outlet is not wired correctly,

cease testing and consult a quali ed electrician.

Power ON the receiver. Before approaching the electrical panel, push
the Power On/Off/Reset button 3 once to reset the receiver. Position
the receiver so that the sensing tip 5 is oriented perpendicular to the
breakers in the panel. Slowly scan all breakers in the panel once, ignoring
any audible or visual indications as the receiver is learning the panel.

Scan all breakers a second time. When the breaker connected to
the circuit with the transmitter is approached, the frequency of the
audible beeps will increase. When located, the audible beep will sound
continuously, the circuit status indicator will illuminate red 9, and the
green indicator in the sensing tip 4 will turn off, indicating that the
correct breaker has been found.

NOTE: Resetting the receiver erases prior scanning data stored from
a previously ‘learned’ panel. Always reset the receiver away from
the electrical panel to ensure that electrical signals are not being
sensed during the reset operation.

CONNECTING TO OTHER FIXTURES USING OPTIONAL ACCESSORIES
(CAT. NO. 69411)

LIGHT SOCKET FIXTURES

Screw the light fixture adapter into an empty light socket. Connect the
transmitter 1 to the 3-to-2 prong adapter, and connect this to the light
fixture adapter. The indicators on the transmitter will communicate an
open ground wiring condition if the light socket is energized. Follow
the instructions in the FINDING CIRCUIT BREAKERS section to find the
correct circuit breaker.

BARE WIRES

The transmitter may be connected to bare wires using the outlet-to­alligator clips wire adapter. Carefully attach the alligator clips the correct
wires. Insert transmitter into the outlet on the wire adapter. The indicators
on the transmitter will communicate an open ground wiring condition if
the wires are energized. Follow the instructions in the FINDING CIRCUIT

MAINTENANCE

BATTERY REPLACEMENT

When the Power-On indicator 4 blinks, the battery must be replaced.

1. Open the battery compartment door 10 by unscrewing the
locking screw.

2. Remove exhausted 9V battery and dispose of appropriately.

3. Replace the 9V battery, close the battery door, and re-fasten the
locking screw.

CLEANING

Be sure unit is turned off and wipe with a clean, dry lint-free cloth.

Do not use abrasive cleaners or solvents. Take care to keep the
sensor lens clean at all times. If required, loose debris may be
removed from lens using clean compressed air. Lens may also be
cleaned using a soft cloth or cotton swab with water or rubbing
alcohol only. Lens must be allowed to completely dry prior to use.

STORAGE

The transmitter 1 may be docked in the transmitter receptacle
in the receiver 2 for convenient storage. Remove the batteries when
the tester will not be used 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.
