GOYOJO TL280 Cable Fault Tester TDR Cable Fault Locator Coaxial Cable Communication Cable Wire Fault Locater Tester 4km

A cable fault tester is a must have tool for those working in the field of networking of coaxial cable. This fault tester has a pretty long distance measurement range of 2.4 miles on auto. The screen is very clear and bright. You can tell someone designed this to be seen easily outdoors during the daytime. Once you understand the functions of the machine, it is easy to navigate. I would have liked to have seen a little longer battery time so that you have a little extra buffer between days, but for the type of device it is, 10 hours is quite a bit. I like the fact that it’s a multi-function cable fault tester as well, making it a more versatile device. Overall, it gives a lot of data, in order to diagnosis the fault problems and is worth the investment.

A really good piece of equipment. It does a snapshot analysis which is helpful. If you need to live monitor an issue it becomes awkward to constantly refresh the scan. I would have given it 5 stars if it did that. Over all it’s pretty easy to use and works well for common troubles

The cable tester came in quickly and with no issues. The TL280 cable fault tester helps you locate coaxial cable communication wire faults. The tester features digital gain automatic control system and the gain can be modified digitally. Eliminate the waveform distortion caused by the potentiometer knob. It can also do pure linear adjustment, which is convenient for manual testing. Using ARM CPU with FPGA technology, can quickly perform various complex operations and determine fault waveform accurately. Digital waveform automatic recognition technology that automatically recognize the waveform that are difficult to determine. Waveform comparison function, it is convenient to compare the test waveform of the fault cable and the normal cable, and clearly find the fault point location. It comes with a high-power lithium battery, which can be used for up to ten hours (with specialized power charger). It has a large-screen LCD color display, interface menu, and is easy for users to operate once you familiarize yourself with the manual. I found this to be a very helpful tool that I use frequently on the job.

If you have an issue within coaxial cables, with a cut signal or a bad one, it's very hard to find the problem. You might have to cut segments to check and narrow down where the problem is, or replace the whole thing. Even professionals replace the whole line when they suspect something is wrong. But that's a waste of course. This little device helps you see the location of the fault, so it's a huge help in productively finding the issue and letting you check and replace just the problem spot. This has impressive distance and accuracy, both important for this type of work. With its solid design and clear screen, there's nothing to complain about with this tool, and its function is beyond helpful if you're trying to locate a fault.

This has turned out to be just an impeccable, irreplaceable tool when the need arises. Not only will it detect breakdown or fault, but will tell you how far down the line said fault is. Saves time, saves money, but is definitely very niche for those that need a tool like this. There is a little learning curve, as the display can be overwhelming if you are not used to it, but once you got it, you got it.
