Using the T-4000 Transmitter
1. Make sure the voltage is not higher than 600V on the conductor you wish to trace.
2. Always connect the banana plugs to the T-4000 before connecting to the circuit.
3. Using the alligator clip cord set, connect the banana plugs to the transmitter.
4. Connect one alligator clip to the wire you wish to trace(it doesn’t matter which one
as the input plugs are not polarized) and the other one to a separate ground.
5. Turn the unit ‘ON’ by pressing on the ON/OFF push button- The screen should
display ‘18888’ briefly. The transmission is ‘OFF’
6. Select the signal transmission level (LOW, MID, HIGH) by pressing on the signal level
push button. It takes about 2 seconds for the transmission to start after you last hit
the push button. (Note: When using the battery booster (B2024 or B2025) the unit
will work in ultra high “U-HI” mode only. Remove the battery booster to return to
normal operation.)
7. Trace the wire with the R-4000 receiver. The signal will stop at the break in the wire.
IMPORTANT: When using the T-4000 in energized circuits with GFCI protection,
always use the Low level transmission.
