01
• Please read and follow all instructions carefully.
The probe of the MS5905R is directional; see the
picture below for usage instructions.
The MS5905T must be connected to the 120V/60Hz
mains for proper use
The MS5905R & MS must be used together for
breaker finder function
When the yellow LED on the MS5905R lights up,

Instructions:
1. Circuit Breaker Finder
A. Plug the MS into an outlet; the middle yellow
LED should light up indicating the line is connected to
the power supply. If the LED does not light, check power
supply or connections to power supply.
B. Move the switch on the MS5905R to the FIND position.
At the circuit breaker panel, take the receiver and run
the tip across the breakers as shown below. The

RECEIVER
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.

2. NCV Non-Contact Voltage Detection
A. Move the Switch on the MS5905R to the NCV position
for Non-Contact Voltage detection.
B. 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.
3. Socket/GFCI Tester
A. Socket Test
• Test on a known good socket before use.
• Plug the transmitter into an outlet, check indicator
lights and refer to the table to determine if the
socket is wired properly.
• If incorrect wiring is indicated, do not use socket.

B. GFCI
• Test on a known good circuit before use.
• Press the test button on the GFCI that you are testing.
If it does not trip, do not use the circuit and consult
and electrician. If it does trip, reset the GFCI.
• Plug the transmitter into GFCI outlet. Press the test
button on the top of the tester for at least 6 seconds.
The indicator lights should turn off and the GFCI
should trip.
• If the tester does not trip the GFCI, the GFCI is
inoperable; do not use GFCI.
