Nf-488 Poe R Inline For Power Over Ethernet Voltage And Current Test Rj45 Network Cable Continuity Dc & Switch Loop-Back Checker

I got 3 cheaper units. All said my ethernet was okay... Lights were fine. I got this to double check....boom, shows that I had a short between wire 1 and 2. Now I have 2.5gbe everywhere. Worth the price for sure.

Perfetto in tutto e per tutto. Eccellente per qualità costo.

Good tester so far, provides all info you need at a glance.

Preisleistung völlig in Ordnung.

There is nothing I dislike about this product so far, but what I do like is the ease of use and the different types of testing in this one product. When working on traffic signal devices, they can be a bit delicate to surges and lightning, having the proper wiring will make all the difference between your equipment being saved or destroyed. The test that I performed was a continuity test with CAT6 shielded direct burial cable, the drain wire/ground must not be connected on the equipment side but must be connected on the supply side, as you can see in the picture it will show that my connection is correct and with one side to ground. Love this tester and I love the price, I would recommend this product.
