UT685B TDR Network Cable Tester Kit

Check wiring, estimate length and trace suitable low-voltage cables with the UT685B TDR network cable tester kit.

✅ See how the cable lines are connected - Line-sequence results on the display help you check the wiring arrangement.

✅ Get a cable-length estimate - TDR testing provides length readings within the listed measurement range.

✅ Follow the cable you are identifying - The cable-tracing probe helps locate the selected cable.

✅ Check supported PoE supply information - PoE detection supports the listed 802.3af and 802.3at standards.

Connect Wiring Checks With Cable Identification

Use the line-sequence view when checking a suitable cable's connections, then use length testing where a distance estimate is needed. The display keeps the selected test information on the instrument.

When identifying a run among other cables, the probe adds a tracing method to the kit. Follow the manual's connection limits for the cable and test being used; this instrument is not for mains wiring.
