Circuit Breaker Finder

Note: The TIS870 Receiver & TIS870 Transmitter must be used together for the breaker finder function.

Connect the TIS870 Transmitter to the 120V/60Hz mains power.
Turn on the TIS870 Receiver.
Move the TIS870 Receiver close to the circuit breaker panel.
Slowly scan the circuit breakers with the TIS870 Receiver until the LED lights up and the buzzer sounds.
The LED and buzzer indicate that the target breaker has been found.

NCV Non-Contact Voltage Detection

Move the switch on the TIS870 Receiver to the NCV position for Non-Contact Voltage detection.
Using the tip of the receiver, move it toward the conductor in question.
If the receiver detects voltage, the LED will flash, and a buzzer will sound.

Socket Test

Move the switch on the face of the TIS870 Transmitter to Socket Test.
Plug the transmitter into a wall outlet.
Note the indicator lights on the face of the TIS870 Transmitter and refer to the following table to determine if the outlet is connected properly or not.

Circuit Breaker Finder

A. Plug the TIS870 Transmitter into an outlet; the red LED should light up indicating the line is connected to the power supply. If the LED does not light, check the power supply or connections to the power supply.
B. Move the switch on the TIS870 Receiver to the FIND position. At the circuit breaker panel, take the receiver and run the tip across the breakers as shown below. The probe is directional, so use other than as shown can give inaccurate results.
C. Run the receiver across the panel a few times. The receiver’s green LED will light up and a buzzer will sound as it learns the panel. After 2-3 passes, the receiver will only react to the breaker that the transmitter is connected to.
D. Flipping off the breaker that the receiver reacts to should turn off the power at the socket the transmitter is connected to. $TIS870-Circuit-Breaker-Finder-fig- $1$$
