    Having confidence in an instrument is an important part of using the instrument. All applications are different and unique. An understanding of the system’s operation could mean the difference between several minutes or several hours on the job. Please read this manual carefully. Take the time to learn how the instrument operates.

  • Page 9 anywhere between the T-4000 and the power source. (Line side or Upstream)- no signal will be present on wiring on the other side of the transmitter(load side or downstream). For example, a transmitter connected to a circuit breaker will produce no signal on that circuit. It will, however, cause a signal to be generated between that panel and the transformer…and beyond.

Remove the battery booster to return to normal operation.) One typical application for the A2202 is to access the hot wire at the panel in order to identify the ‘downstream’...

  • Page 14: Finding Ground Faults

    Select the ‘HIGH’ sensitivity by pressing the SENSITIVITY push button (the LED must be ‘ON’). Starting from the T-4000, trace the conductor. The open will be at the point you begin to lose signal. At that point, select the ‘MID’ sensitivity mode (the LED must be ‘blinking’) in order to pinpoint the exact location of the Open.

  • Page 15: Tracing Wires In Conduit

    Attach one clip to the faulted wire and the other one to ground. Press the signal level push button and select the appropriate level. If possible, ground all adjacent conductors. The R-4000CON receiver can then be used to trace the wire. The signal should remain relatively constant until you pass the ground fault.

    If two or more breakers produce the same signal strength indication. Move the receiver away slowly from each of them and watch the indication level. (Refer to Figure 17) Tracing Energized Wires Connect the Alligator Clip Cord set to the T-4000. Make sure the voltage does not exceed the T-4000 rating.
