Review on Identify Standards Physical Presence 50V 1000V by Alex Montgomery

It does exactly what it says on the tin - tests your Cat cables to make sure they're done right. The longest distance I've tried is about 70 feet, and it worked great for that. If you're using shielded cable like I am, this will also be checked. The instructions are pretty bad, but you don't need them - just remember to long press to toggle on/off, then just follow the simple menus. He found that the existing cable I was extending was not properly connected - one end was A and the other B - and clearly showed cross connections on the display. I cut off the plug, made new - the problem is solved. Worth the price. When you make cables, you need some kind of tester, and this is a good tester for beginners. Will something like high-end trematodes do it? Can he certify that you meet the requirements of Category 6/6A? no But it's 1/10 the price and will tell you clearly if there are any shorts, crossovers, openings etc basics and it does it at a great price.
