help Klein Tools ET500 Network Cable Tester FAQ
What types of network cables can the Klein ET500 test?
The ET500 tests UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) Ethernet cables including Cat5e, Cat6, and Cat6a cables with standard RJ45 connectors. It performs wiremap, continuity, and length tests.
Does the ET500 require batteries to operate?
Yes, the Klein ET500 uses a standard 9V battery for power. Battery life depends on usage frequency, but LEDs are generally energy-efficient. Always check battery level before starting critical cable testing jobs.
Can this tester measure the exact length of a cable run?
The ET500 measures cable length up to its maximum range, which is suitable for most residential and small commercial installations. While useful for quick length verification, it may not provide laboratory-grade accuracy for documentation purposes.
Is the ET500 suitable for professional network installers?
The ET500 works well for basic verification and troubleshooting by professionals, but it lacks advanced diagnostics like time-domain reflectometry (TDR) or the ability to certify cable performance. Professionals needing certification may prefer higher-end models.
Can this tester detect where a cable fault is located?
The ET500 identifies pass/fail status and approximate cable length but cannot pinpoint the exact location of faults like breaks or shorts along the cable length. For fault location, a TDR-based tester would be required.
