Page 4: Precautions & Introduction
The AMPROBE ATP SPX current tracer has a history of providing safe, reliable operation in tracing energized wires, locating circuit breakers and locating wires shorted to the ground. The AMPROBE ATP SPX open tracer has the capability of tracing unenergized wires, locating open breakers and locating open wires. -
Page 5: Product Description
AT-4000 PRODUCT DESCRIPTION The AT-4000 consists of two units: T-4000 Transmitter (32.768KHZ, 9-600 volts AC or DC) R-4000 Receiver(Non-position sensitive, Open / Short Tracing) Unit Description R-4000 Receiver: It has two built in detectors that are tuned to pick up the 32.768Khz signals generated by the T-4000 transmitter. - Page 6 When connecting to a circuit as a load, the signal will be present 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.
- Page 7 Fig.2 T-4000 Transmitter Continued LIVE U-Hi HIGH “ “ U U - - H H I I ” ” - Transmission Ultra High: Battery booster is in use. To return to normal operation, remove the battery booster. A2202 Clamp-On Transmitter Accessory Enables the T-4000 to induce its signal onto an unenergized or energized circuit.
- Page 8 B2024 Battery Pack 24 Volt Nickel-Cadmium rechargeable cell custom designed for light weight, small size, and durability. Used to boost the output of the T-4000. Consult the specs for the boost levels. Includes a self-resetable fuse. Be sure to charge fully before use. (DO not use the B2024 when tracing energized lines.) Note: When using the battery booster (B2024 or B2025) the unit will work in ultra high “U-HI”...

APPLICATION NOTES Using the R-4000 Receiver 1. Turn the R-4000 ‘ON’ by pressing the Power ON/OFF push button. 2. Select the ‘High’ sensitivity by pressing the sensitivity push button(LED ‘ON’). 3. Select the appropriate mode by pressing the MODE push button (LED ‘ON’: Open tracing;... -
Page 11: Using The T-4000
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. - Page 12 The signal generated by the T-4000 is present at all points around the circuit. The T-4000 connected to a 110V outlet via the C2901 cord set will cause an incoming signal on the neutral wire as well as an outgoing signal on the hot wire. The close proximity of these two wires may cause the signals to cancel each other, making it difficult to trace the cable in these areas.
- Page 13 Easy tracing of wires and buried cable is accomplished by simply separating wire from the return path (ground). Instead of using the neutral wire or the conduit as the ground, use the C2902 Alligator Clip cord set and attach the grounding test lead to a separate ground such as a water pipe.

Page 14: A2202 Clamp-On Transmitter Accessory
Using the A2202 Clamp-On Transmitter Accessory The A2202 will allow non-contact signal indication onto energized or non-energized conductors. On energized lines, the signal will propagate downstream to the end of the circuit, provided there is a current flowing in the circuit. Unenergized lines must be grounded at both ends or made into a complete circuit. -
Page 15: Finding Opens
Finding Opens ‘Opens’ are dead-end conductors that are not connected to anything and therefore do not pass current. To find an Open, use the T-4000 transmitter, R-4000 receiver, and the alligator clip cord set. (Refer to figure 15) 1. Plug the two banana plugs into the T-4000 2. -
Page 16: Finding Ground Faults
Finding Ground Faults A ground fault is a direct connection of the conductor to ground. A typical ground fault may cause a tripped circuit breaker or a blown fuse ( in contrast to an ‘open’, which passes no current). In this situation, the B2024 battery can be used as the current source. -
Page 17: Tracing Wires In Conduit
Tracing Wires in Conduit When seeking a ground fault within metal conduit, the ‘ground’ is the conduit. Connect one of the clips to the conduit to complete the circuit. Steel conduit will tend to attenuate the signal strength so tracing will require higher sensi- tivity levels and access to within a few feet of the conduit. -
Page 18: Tracing Wires
Tracing Energized Wires 1. Connect the Alligator Clip Cord set to the T-4000. 2. Make sure the voltage does not exceed the T-4000 rating. 3. Connect one alligator clip to the hot wire and the other to a separate ground. At a receptacle, use the C2901 Pigtail to access the hot wire. - Page 19 Locating Outlets From The Breakers Panel 1. Connect the A2202 Clamp-on to the T-4000 Transmitter and then clamp it around the conductor. 2. Set the T-4000 to ‘HIGH’ signal level. 3. Set the R-4000 to ‘OPEN’ mode and ‘LOW’ sensitivity. 4.
