Review: Good ethernet test. - I bought this because I lost my fluke and needed something but not as expensive. Over all I'm happy, as I didn't really expect much from the price. The tester is more rugged than I thought it has all the same tests that the fluke had done and screen looks similar when testing. This has a 3 position switch one for scanning. This if for use with probe to locate wires it produces tone that probe picks up. Second it cable testing it does ethernet and coax and #3 is poe. When testing twisted pair you can test individual pairs. The fluke is a bit more responsive in how fast it aquires info. But so far this is working out great. It is a little bigger than my fluke was but only in length by maybe half inch. So far this has been working well for what I need and I got the added probe with it allowing finding buried wires a plus. I would recommend.

It has TDR technology to test the cable length, cable ID and fault point distance without blind spots, and uses a graphical display interface. At the same time, it can test RJ11, RJ45 and coaxial cable types, and can identify POE standards.
- 【POE TESTING】: Can detect whether there is PoE power supply (Power over Ethernet module) and PoE standards (802.3AF, 802.3AT, 802.3BT) in the network cabling.
- 【ADJUSTABLE SENSITIVITY】:When the receiving signal is weak, turn up the gear When the received signal is strong, turn down the gear.
- 【NCV DETECTION】: Press the "NCV" button on the receiver to turn on the NCV function. When the target cable or socket is carrying more than 40V AC, the receiver will beep and beep, and the "NCV" indicator will flash synchronously to ensure the safe operation of personnel.
- 【WIDELY USED】: Network installation, computer room maintenance and other daily network communication scenarios, engineering wiring, coaxial cable measurement.
