It might be worth noting that if you are dealing with higher frequency system(such as Wi-Fi antenna feeding cable) then the test might not be good enough, you could have a cable that shows continuity but is extremely lossy when used, just something to be aware of.

A few years ago, my TV reception went dead. I'm on a subscribed satellite dish plan. I tried changing the dish, then the receiver, neither one worked. Friends said it must be the TV, which wasn't that old, but I wanted to upgrade to a new, larger flat screen anyway, so I spent $1200 on a nice new large flat screen TV. Still, no picture. Finally, I bought a new coaxial cable for $19.95 and voila....TV worked. It was likely the cable, all along.

I do this the same way but it is a little easier with something I made. I took a female, F-type connector, (the type of connector that screws in to a standard TV coax connector) I removed the barrel/cover from the rear of the F-type connector. I then soldered a short wire and clip to the center wire/pin/stinger on the rear side of the F-type connector. I now keep it with my test leads. When I need to test coax, I simply screw this thing on the opposite end of the coax cable line. It is easier than trying to get alligator tester clips on the coax connectors. I can also use it for an open circuit or closed/shorted test on any length of coax in the building.

Why did you not check the outer in inner core seperate? Testing both at the same time does not tell you if the inner core for example is snapped as the current will go down the outer braid also.
@StagnatedOrc
@StagnatedOrc 6 жыл бұрын
The alligator clips connect the inner core to the outer shielding, essentially creating one long conductor. If the inner core were snapped, the current would not even make it to the alligator connector at the other end -- it would still read 0.L as it did with his first test.

@mightymulatto3000 5 жыл бұрын
@@ACommenterOnKZbin Impedance can't be checked directly with an Ohm meter due to its capacitive and inductive elements. Even the formulas for capacitive and inductive reactance aren't practical to use when working with cables but they are reduced to taking the log of the diameter of the outer braid shield divided by the diameter of the center conductor and multiplying by 138. If any of those physical characteristics changed due to damage the above test although quite useful wouldn't reveal it.

@billeaglerunner6844
@billeaglerunner6844 9 жыл бұрын
***** No it does not mean the wire should read 75 ohms. 75 ohm cable is designed for impedance matching for the system it is being used in. Its all about voltage and current. Hard to explain. Maybe this website can help www.bluejeanscable.com/articles/impedance.htm. Hope I answered your question.
@mightymulatto3000
@mightymulatto3000 5 жыл бұрын
The 75 Ohms is actually what is known as the characteristic impedance of the cable. The cable has capacitive reactance along with inductive reactance that has to be accounted for at signal higher frequencies. More importantly however maximum power transfer from a source to it's load only happens when the signal source, cable, connectors and load impedances match. This is why when you look at camera specs you'll see 75 Ohms listed. Since this impedance can't be measured directly the test here is good for continuity. However it won't let you know if the other physical characteristics of the cable are what they need to be for the considerations above. It can be argued that most techs don't need fancy cable testers but some of them actually give you the impedance of the cable.

Don't waste your time doing that, just call your cable company and have them put the real good ones at no charge, that if you have them for service.
