Precautions
FOR PERSONAL AND INSTRUMENT PROTECTION
IMPORTANT:
1.Before using any electrical instrument, it should be checked to make certain it is operating properly.
2.In many instances, you will be working with dangerous levels of voltages and/or current, therefore, it is important that you avoid direct contact with any uninsulated, current carrying surfaces.
Appropriate insulated gloves and protective clothing should be worn.
3.Before attaching any of the conductors, make sure the voltage present is not beyond the range of the instrument.
4.When not in use, keep the instruments in their carrying case.
5.When the R-4000CON or the T-4000 will not be used for a period of time, remove the battery to prevent leakage in the instrument.
Introduction
AMPROBE ATP SPX is dedicated to designing, manufacturing and marketing high quality, reliable instruments for the skilled professional. 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.
The AT-4000CON Wire Tracer Upgrade System combines both the current tracing CT100 and the AT-2000 series into one versatile tool providing the ability to solve virtually all your tracing problems. In addition to the above features, the receiver provides a non position sensitive when tracing wire and the transmitter provides a visual indication to the user when the traced line is energized. The level of the signal transmission is also indicated on the LCD of the transmitter unit.

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. The operation is user friendly and easy to learn. Test it in a variety of situations. You will soon have the confidence
to use it on a daily basis to solve problems that were previously unsolvable.
AT-4000CON Product Description
The AT-4000CON consists of two units:
T-4000 Transmitter (32.768KHZ, 9-600 volts AC or DC)
R-4000CON Receiver(Non-position sensitive, Open / Short Tracing)
Unit Description
R-4000CON Receiver
It has two built in detectors that are tuned to pick up the 32.768Khz signals generated by the T-4000 transmitter. The R-4000CON is designed to display the signal strength to enable quick locating of the conductor carrying the signal.
T-4000 Transmitter
When connected to an energized circuit, the T-4000 will filter the low frequencies up to 400Hz and rapidly indicate on the display that the wire is energized. When the user starts the transmission, a combination of signals is injected on top of the 50, 60, or 400Hz that cause a slight, periodic current fluctuation and allows the power line to emit its
own, traceable signal. This signal can be detected back to the main generator. However, the signal will not interfere with any sensitive electronic equipment and does not require power interruption. The unit is intrinsically safe and has a ‘LOW’ signal transmission setting that must be used when tracing GFCI-protected circuits.
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. It will, however, cause a signal to be generated between that panel and the transformer…and beyond. When connecting to an unenergized circuit, the live indication on the display will remain ‘OFF’. When the user starts the transmission, the transmitter injects a combination of signals onto the conductor. The signal will travel along the conductor until it ends. There is no difference in the functional mode of the unit when tracing energized circuit and unenergized circuits. On an open line, no current will flow, so the injected signal will present itself as a voltage spike along the wire which is detected by the R-4000CON in the ‘OPEN’ mode. When the conductor is part of a complete circuit, the voltage causes a current to flow which produces a signal that is
detected in the ‘SHORT’ mode. The T-4000 contains a 9V battery. A 24V input jack accepts the B2024 rechargeable battery or the B2025 110V converter, both use when a very strong signal is necessary.
(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.)
A2202 Clamp-On Transmitter Accessory
Enables the T-4000 to induce its signal onto an unenergized or energized circuit. Plug the A2202 into the T4000 and clamp it around any conductor in an unenergized circuit, or the hot wire in an energized circuit. The signal will be induced on top of the 50,60,or 400Hz frequency which may be present. The AT2201 acts like a 1/2 Volt battery when clamped around a conductor. On a complete circuit this voltage will cause about 80mA of current to flow on top of the whatever frequency is present.
To increase the signal strength, loop the wire around the clamp a few times or use the B2024 battery Pack. The A2202 will allow wire tracing without the need for direct connection. (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.)
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” mode only. Remove the battery booster to return to normal operation.
B2025 110V Converter/Recharger
Can be used to either recharge the B2024 or directly boost the T-4000. To recharge the battery, leave it connected for at least 8 hours. (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” mode only. Remove the battery booster to return to normal operation.
