WARNINGS - NCV FUNCTION

• When NCV Function is initiated, a blinking or steady green glow and an audible

beep indicate voltage present. If no indication, voltage could still be present.

• Before and after each use of the NCVT, verify operation by testing a known

working circuit that is within the rating of this unit.

• Never assume neutral or ground wires are de-energized. Neutrals in multi-wire

branch circuits may be energized when disconnected and must be retested

before handling.

• The NCV tester WILL NOT detect voltage if:

• The wire is shielded.

• The operator is not grounded or is otherwise isolated from an effective earth

ground.

• The voltage is DC.

• The NCV tester MAY NOT detect voltage if:

• The user is not holding the tester.

• The user is insulated from the tester with a glove or other materials.

• The wire is partially buried or in a grounded metal conduit.

• The tester is at a distance from the voltage source.

• The field created by the voltage source is blocked, dampened, or otherwise

interfered with.

• The frequency of the voltage is not a perfect sine wave between 50 and 500Hz.

• The tester is outside of operation conditions (listed in Specifications section).

• Operation may be affected by differences in socket design and insulation

thickness and type; tester may not be compatible with some types of standard

or tamper resistant (TR) electrical outlets.

• Do not apply to uninsulated hazardous live conductors.

• Detection above 50V is specified under “normal” conditions as specified below.

The tester may detect at a different threshold at different conditions, or may not

detect at all unless:

• The tip of the tester is within 0.25" of an AC voltage source radiating

unimpeded.

• The user is holding the body of the tester with his or her bare hand.

OPERATING INSTRUCTIONS

Before testing, verify the Receiver is functioning properly by placing

it near the powered Transmitter. With the Receiver set to Sensitivity

Level 8, a numerical reading of 99, all 10 signal strength bars lit up,

and a strong audible signal confirms the system is working. The

Receiver will produce a variable beep proportional to the sensitivity

value. The higher the signal strength, the faster it will beep.

NOTE: A continuous beep or solid-on LED indicates strongest

possible signal of 99 and the Receiver is saturated.

NOTE: If the Transmitter is powered up normally but the Receiver

detects a very low signal level, even when set to the highest

sensitivity level, the internal protection fuse in the Transmitter

should be checked, as it may be blown.

CONNECTING TEST LEADS

Connect test leads by inserting the black lead into the "COM" jack and

the red lead into the "+ 600V" jack. Do not test if leads are improperly

seated. Results could cause intermittent display readings. To ensure

proper connection, firmly press leads into the input jack completely.

NOTE: Test leads used must have a CAT III 600V safety rating.

OPERATING INSTRUCTIONS

TRANSMITTER DIRECT AND REMOTE GROUND CONNECTION METHODS

DIRECT GROUND: In a direct ground connection, a plug or clips can

be connected to the hot and neutral wires on the same circuit.

NOTE: While locating a breaker, the wires will not be as traceable due

to the cancellation effects of the wires running parallel.

REMOTE GROUND: Preferred for optimum signal strength. To optimize

the transmitted signal and avoid cancellation effects which occur in a

direct ground connection, a remote ground connection should be used.

Attach the Ground Prong

to the 20' (6 m) Lead Adapter

and

connect to the ground of an outlet on a different circuit. Attach the red

Blade Prong

to the red test lead

and connect to the hot wire of

the circuit you are tracing.

NOTE: This Remote Ground connection method will trip GFCI receptacles.

Several workarounds are available: Use the Direct Ground method,

connect directly to wires with alligator clips

, or de-energize circuit by

turning off breaker at the panel.

OPERATING INSTRUCTIONS

RECEIVER ORIENTATION

The orientation of the Receiver in relation to the wire being traced is very

important. The vertical Crosshair Groove

on the tip of the Receiver

indicates the preferred direction of the wire for the strongest signal

detection. While tracing a wire, rotate the Receiver to always ensure the

highest signal value is displayed. The signal may not be detected if the

Receiver tip is not properly aligned to the wire. If the signal drops, the wire

may have changed direction (horizontal to vertical or vertical to horizontal).

Whenever possible, keep the Receiver at least 3' (0.9 m) away from the

Transmitter and test leads to reduce signal interference.

APPLICATIONS

Circuit Breaker Finder (energized and de-energized)

1. Connect the Transmitter to the circuit to be identified using either the direct

ground or remote ground connection and power the Transmitter on. The

direct ground and remote ground connection methods can be used on both

energized and de-energized circuits, but an energized circuit produces a higher

signal strength.

2. Verify that the Energized Indicator on the Transmitter is illuminated if

connected to a circuit with voltage above 25V AC/DC and is not illuminated for

de-energized circuits.

3. Go to the electrical panel and power on the Receiver. If there is more than one

panel, touch the tip of the Receiver to each panel cover to identify the panel

with the highest signal level. Use the Increase Sensitivity

and Decrease

Sensitivity

buttons to adjust the Receiver sensitivity level to identify the

panel with the highest reading.

4. Once the panel has been identified, open the cover.

5. Orient the Receiver facing left or right and perpendicular to the breakers (See

below). Slowly move the Receiver up and down in front of each breaker. Use

the Increase Sensitivity

and Decrease Sensitivity

buttons to adjust the Receiver sensitivity levels as

needed to locate the breaker with the highest reading.

After any sensitivity level changes, rescan all the

breakers to find the breaker with

the highest reading.

NOTE: Energized circuits typically use

sensitivity levels 1-3, and de-energized circuits may need

higher sensitivity levels 4-8.

NOTE: If two or more breakers have the same signal value,

remove the panel cover and place the tip of the Receiver on

the individual wires to help in determining the correct breaker.

NOTE: Ensure the wire is held in the proper orientation in

relation to the tip of the Receiver.
