I got this one for free for an unbiased review. I work in the telecom/internet industry and use Ethernet a lot. Along with repairing if damaged/bad. So I couldn't pass up testing this counter. I have an ethernet tester that I've been using for years, but it only showed if it was connected well/correctly. This one does the same thing, along with a few other features. I did all my testing with 3 different CAT6 ethernet cables. The cable used for testing was 10 feet, 15 feet, and 50 feet in length. First I checked the distance values. It was pretty accurate in meters and feet. The only thing I didn't like was that every time I turned on the device I had to reset it. The default is meters. I then tested the match test with all 8 adapters and what was nice was that it told me which adapter was connected. That way, if you're working on multiple launches at the same time, you can tell which is which. Start having fun now. First, I hooked one of the wires and held it up to look at the map and footage. This gave me the distance of each pair and could tell me where was open. A short simply says SHT for the pair that was shorted. Wire distribution was good meaning it showed up when I connected one side to A and the other to B. This showed that 1 2 and 3 6 were reversed. The advantage of the indicator is that when the wire opened, it indicated that the pair was open. But that was also a problem. The counter I've used for years also shows when a pair doesn't fit, but this one should have shown more. For example which wire and which side. The instructions indicate this should show an open circuit and which end of the wire (instruction picture attached). But the counter showed it as an open pair and didn't determine which side, near end or far end. There is a note in the instructions saying this can happen, but directly above show me which wire and which end was open. It would be nice if he did. You can clearly see in fig. I left 1 wire at the end for this test. The meter has a sticker stating that it cannot be used with a POE circuit with a voltage >20 VDC. But the indicated directions are connected no more than 60V. This is contrary to what the counter shows. Personally, I would NEVER connect this to any cable of any voltage. Check only with de-energized cables/lines. In the end because of the cost of the counter and the functions it can perform. It's definitely worth the price. Keep in mind that this is not a high-end meter. If it were high end the cost would be MUCH higher than it's worth. And it's probably from China. For this reason, gauges are likely to continue to be used as standard. Not the end of the world, it just takes a few extra seconds to get back on your feet. If you are looking for an Ethernet tester at a great price, I would buy this meter. It's worth the cost.
