INtRodUCtIoN
The Amprobe AT-5000 Utility Locator with Sheath Fault Locating (SFL) option is designed to detect and pinpoint sheath and
other conductor faults that are in direct contact with the earth.
The AT-5000 with A-5000 (SFL) offers these unique features:
Fault level measurement at the transmitter •
Simultaneous fault finding and line tracing •
LCD bar graph representing the A-Frame signal strength for judging the proximity to faults, comparing multiple faults, and •
detecting pinholes and “trees” in a power cable
Detection of low and high resistance faults
•
Automatic battery checking and low battery warning •
Non-polarized A-Frame •
Single-handed operation. No need to carry an R-5000 receiver as well as an A-frame during fault locating •
Active SFL ohmmeter and voltmeter in the Transmitter •

Safety Precautions
observed safety practices
Familiarize yourself with all required safety practices of the local utility company, or other owner of the plant before entering an
access area, or connecting an Amprobe transmitter.
Ensure that the line is de-energized and out of service, BEFORE connecting the transmitter directly to any conductor. NEVER
make a direct connection to a live power cable.
Follow the appropriate safety procedures to avoid the risk of injury if using a clamp on energized electrical or control lines.
Pay special attention when using a locator in high traffic areas.
Intended application
Safe operation is only realized when using the equipment for its intended purpose. Using the equipment for other purposes
may lead to human danger and equipment damage.
The limits described under the technical data section may not be exceeded.

Check Batteries Prior to Departing for the Field 1.
Check the battery level in the Transmitter, Receiver, and A-Frame by powering up each instrument.
Maximum use of the Transmitter’s SFL feature requires that the battery be fully-charged prior to field use. Amprobe
recommends charging the battery to full capacity before locating faults.
Replace/recharge if necessary. Turn the instruments OFF.
Ensure All Conductors Are De-Energized
2.
Lift Grounds 3.
Lift Grounds (of all conductors in the circuit) at both ends of the faulted cable section.
WARNING When the t-5000 transmitter is oN, the external oUtPUt JACk produces a high voltage. do not touch the jack!
Electrical shock will result!
Attach Transmitter to Conductor – Check Fault Resistance 4.
Make sure T-5000 transmitter is powered OFF. 1.
