6. Test the unit on a known functioning circuit or component.
(Receptable should be NEMA 5-15R with 100 to 125 VAC,
50 to 60 Hz.)
• If the unit does not function as expected on a known functioning
circuit, replace the battery in the receiver (2012-R).
• If the unit still does not function as expected, send the unit to
Greenlee for repair.
Tracing a Circuit
1. Set up the transmitter and receiver as described in Setup above.
2. Beginning at the transmitter, move the receiver in a sweeping
motion along the wall, floor or ceiling.
3. Using the tone and “H” display as a guide, trace the wiring. Adjust
the sensitivity according to the material of the wall, floor or ceiling.
• Decrease the signal’s intensity (and the receiver’s tone) by
turning the knob clockwise.
• Increase the signal’s intensity (and the receiver’s tone) by
turning the knob counterclockwise.
Note: If the signal becomes lost during this procedure, continue on to
where the circuit is likely to end (a junction box or fuse panel) and trace
back to the transmitter.
Locating a Circuit Breaker
1. Set up the transmitter and receiver as described in Setup above.
2. Slowly move the receiver toward the circuit breaker panel.
The ON/Pulse LED will blink and an “H” will appear on the display.
A series of tones will begin. The “H” will help distinguish the real
signal from interference or line noise.
