Who tests hereby tested properly.

Since the good old method is obsolete there with a car battery and the tongue at the other end, I opted for the cable tester Wentronic. Very good cable tester, for both USB as well as for telephone and LAN cable.

After I had only a product of the brand Upper scrap, I changed after a colleague I have this model can try. Very chic, very easy to use, illustrated very understandable.
The whole thing comes with a small booklet and hand in a simple black bag and is due to the size already excellent takeaway. Warning, the battery is not present - is needed plus a 9V.

Hopefully it will not come in the dubious pleasure to review a BNC network for problems, but alone the fact that it was up, calmed me immensely ;-)

I can only recommend, 1A product has been properly survived several operations.
