Network cable tester YATO YT-73137 — cable locator and wire tester for network and telephone lines

YATO YT-73137 is a network cable locator and wire tester designed for checking network and telephone lines. It detects cable continuity and helps locate individual pairs and faults in structured cabling. The tool is intended for installers and technicians who need a compact tester to speed up diagnostics, maintenance and troubleshooting of Ethernet and phone circuits.

Advantages

The YATO YT-73137 combines cable locating and basic continuity testing functions in a single handheld unit. It provides clear indication of open, short or crossed pairs and aids in identifying individual conductors within multi-pair cables. The compact form factor and straightforward operation reduce inspection time on site and simplify repetitive testing tasks for network and telephone cabling.

Suitable for

• Installation and verification of Ethernet twisted-pair cabling
• Testing and tracing telephone lines and patch cords
• Fault finding in structured cabling during maintenance
• Field service and on-site network troubleshooting

Key specifications

• Function: cable locator and wire continuity tester for network and telephone lines
• Detectable conditions: continuity, open circuit, short circuit, pair identification
• Cable types supported: twisted-pair network cables and standard telephone lines
• Form factor: handheld tester with remote terminator for pair tracing

How to use

Connect the main unit to one end of the cable and attach the remote terminator to the other end or to the suspected line. Power the tester according to the manufacturer's instructions and select the appropriate test mode. Observe the indicator signals to determine continuity status and pair mapping; use the locator function to trace cable runs and identify individual conductors. Follow standard safety procedures when working with live circuits and disconnect power where required before testing.

Usage recommendations

For reliable results, test cables with both ends accessible when possible and verify findings by performing repeat tests. Use the remote terminator to isolate specific pairs and label cables after verification to simplify future maintenance. Store the unit and accessories in a dry environment and replace batteries promptly to maintain accurate indicators.
