Safety Information

• The BT-120 Breakers Tester is conformed to UL 61010-1; CAT II 120 V, class
II and pollution degree 1 or 2.

• The BT-250 Breakers Tester is conformed to UL 61010-1; CAT II 250 V, class
II and pollution degree 1 or 2.

Warning and precaution

• Before and after hazardous voltage measurements, test the voltage
function on a known source such as line voltage to determine proper
meter functioning.

• Do not touch the membrance.

• Inspect the receiver and the transmitter before every use. Do not use any
damaged part.

• Never ground yourself when taking measurements. Do not touch
exposed circuit elements or test probe tips.

• Do not operate the instrument in an explosive atmosphere.

2

• To reduce the risk of fire or electric shock, do not expose this product to
rain or moisture.

• The meter is intended only for indoor use. To avoid electrical shock
hazard, observe the proper safety precautions when working with
voltages above 60 VDC, 42.4 Vpk, or 30 VAC rms. These voltage levels
pose a potential shock hazard to the user.

OPERATION

Breaker and Fuse Identification

1. Plug the Transmitter into an energized wall outlet (Figure 1).

Transmitter

Circuit Tracer

Figure 1

2. Make sure the red LED is ON to indicate that the outlet is energized.

3. Push the Power switch on the Receiver to turn it ON. The Receiver will
beep and the Power LED will be lit.

4. At the breaker panel or fuse box, hold the Receiver perpendicular to the
breakers. Scan slowly all breakers once to calibrate the Receiver. During
this scan, the Receiver may beep and flash at several breakers. This is a
normal part of the identification process (Figure 2).

5. Without touching the ON/OFF button, begin scanning again to identify
the right breaker or fuse. When the Receiver beeps, the correct breaker
has been identified.

6. Push and hold the Power switch for three seconds to turn the Receiver
off. Beeping and flashing during the shutdown is normal.

7. Unplug the Transmitter from the wall outlet.

Using the BT-LFA Incandescent Light Fixture Adapter (BT-250 only)

1. Remove the light bulb exercising the proper caution.

2. Screw in the BT-LFA adapter.

3. Plug the Transmitter into the BT-LFA (Figure 3).

Figure 3

4. Preform scan following directions in step 4 under “Operation.”

Using the BT-VLA High Voltage Leads Adapter (BT-250 only)

The BT-250 Transmitter can be used alone on 110V circuits. For circuits up to
250V or exposed circuits, use the BT-VLA and follow the directions listed below.

1. Plug Transmitter into high voltage lead receptacle. Be sure that the
Transmitter is completely seated and that no part of the Transmitter
prongs are exposed.

2. Attach the high voltage leads to the terminal or conductor while
exercising extreme caution (Figure 4).

3. Preform scan following directions in step 4 under “Operation.”

MAINTENANCE AND REPAIR

If there appears to be a malfunction during the operation of the tracer, the
following steps should be performed in order to isolate the cause of the
problem.

1. Check the battery. Replace the battery immediately if the Receiver LED
doesn’t turn ON.

2. Review the operating instructions for possible mistakes in operating
procedure.

Except for the replacement of the battery, repair of the tracer should be
performed only by a Factory Authorized Service Center or by other qualified

The front panel and case can be cleaned with a mild solution of detergent and
water. Apply sparingly with a soft cloth and allow to dry completely before
using. Do not use aromatic hydrocarbons or chlorinated solvents for cleaning.
