IMPORTANT: Always conclude your tracing with the “MID” or “LOW”
sensitivity because the built-in detector has a 360° detection range.
It will be a good idea to have the transmitter on the low signal
transmission depending on the length of the wire you are tracing.
5. When tracing, move the R-4000 back and forth slowly over the
path of the wire. The strongest signal confirms the path of the
wire.
Using the T-4000-A Transmitter
1. Make sure the voltage is not higher than 300V on the conductor
you wish to trace.
2. Always connect the banana plugs to the T-4000-A 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’
