Operation

WARNING: Always test on a known good circuit before use.

WARNING: Refer all indicated problems to a qualified electrician.

Locating a Circuit Breaker or Fuse

The transmitter injects a signal onto the circuit which can be detected by the receiver. The receiver will beep when the signal is detected. The sensitivity adjustment allows for tracing and pinpointing the exact circuit breaker or fuse protecting the selected circuit.

1. Plug the Transmitter / Receptacle Tester into a powered outlet. The two green LEDs should illuminate.
2. Rotate the Receiver’s Sensitivity adjustment from the OFF position to the HI position. The red LED should turn on. If the LED does not turn on, replace the battery.
3. Test the operation of the Receiver by placing it in close proximity to the transmitter. The receiver should beep and the LED should flash.
4. At the breaker panel, set the sensitivity to the HI position and hold the receiver as indicated by the “UP — DOWN” label.
5. Move the receiver along the row of breakers until the selected circuit is identified by the beep and flashing light.
6. Reduce the sensitivity as needed to pinpoint the exact circuit breaker controlling the circuit.

Receptacle Wiring Test

• CORRECT WIRING
• GFCI TESTING IN PROGRESS
• HOT ON NEUTRAL WITH HOT OPEN
• HOT AND GROUND REVERSED
• HOT AND NEUTRAL REVERSED
• OPEN HOT
• OPEN NEUTRAL
• OPEN GROUND
• OFF ON

1. Plug the Transmitter / Receptacle tester into the outlet.
2. The three LEDs will indicate the circuit condition. The diagram lists all of the conditions that the CB10 can detect. The LEDs in this diagram represent the view from the GFCI button side of the transmitter. When viewing the other side of the transmitter the LEDs will be a mirror image of those shown here.
3. The tester will not indicate the quality of the ground connection, 2 hot wires in a circuit, a combination of defects, or reversal of ground and neutral conductors.

Receptacle GFCI Test

1. Before using the tester, press the TEST button on the installed GFCI receptacle; the GFCI should trip. If it does not trip, do not use the circuit and call a qualified electrician. If it does trip, press the RESET button on the receptacle.
2. Plug the Transmitter / Receptacle tester into the outlet. Verify that the wiring is correct as described above.
3. Press and hold the test button on the tester for at least 8 seconds; the indicator lights on the tester will shut off when the GFCI trips.
4. If the circuit does not trip, either the GFCI is operable but the wiring is incorrect, or the wiring is correct and the GFCI is inoperable.

Replacing the Battery

1. When the battery drops below the operating voltage the receiver’s LED will not light. The battery should be replaced.
2. Remove the receiver battery cover by removing the screw using a Philips head screwdriver. (The Transmitter is line powered.)
3. Install 9 volt battery observing the correct polarity. Re-install the battery cover.
4. Dispose of the old battery properly.
