How do you "ring-out" electrical system?
Answers: To "ring-out" wiring is simple. A typical electric wiring harness has several cores (wires) within it, that go duplicate or different places. To ring-out a cable, you apply a know signal on one end of one of the cores and verify that it is coming out the other expire of the cable. Using a tone generator and inductive amp is the most common mode of doing this. This is used to verify that there are no breaks surrounded by your wiring, intent all the cores are competent to pass a signal. You can also do this to see if two or more cores are shorted together, which will typically do problems.
If the cable is short enough, or you own both ends together, you can use a standard multi-meter to Ohm the cable out. This is same as using a generator and enductive amp, but the signal generator and receiver are matching device, the multi-meter.
To do this yourself, you need one of the two types of equipment down above. A multi-meter can be gotten for as little as $10-15. A "Fox and Hound" (Tone generator and inductive amp) will run a little more. Typically $40-50. You also have need of to know the correct pin-out of the cable. That means you know which pin on respectively end is supposed to dance to which pin on the other end. Simple coax cable are one core and rather unambiguous. Ethernet cable has eight lines and is usually color coded. There are testers for ethernet cable that can be as low as $25 up to the $1200 ones we use.
The process is simple. Apply signal to one end of the core and check for it at the other. Depending on which method you use, the instructions beside the device should explain how to do it, with the exception of the multi-meter. To use a MM to Ohm the cable, set your MM to Ohms (The horseshoe looking symbol) apply one of the lead to one end of the cable and the other front to the other end of the cable, on alike core. Depending on the length of the cable, the core composition and several other factor, you will get a reading on the meter. 0.0 is immaculately conductive (no resistance) but you won't get that. For a shorter coax cable (20' or less), you should take a reading of about 0.3 or 0.4. To verify that the cable isn't shorted, give up your job the lead on the core at one wrapping up and use the other to check the other cores and shield. If you get a reading of lower than 100 Ohms on them, there is a short. The lower the number, the stronger the short. Some cable have a cross-over (short) purposefully. This is where on earth you need to know the electrical system pin-out.
I know this seems long, and possibly confusing, but I'm not sure of your stratum of expertise with electronics. I hope this help.
I think you scrounging "Wring Out." It's an old residence, I originally heard it used beside wet laundry - tr dry a shirt, you help yourself to the shirt and tightly twist it up, this will force excess marine out of it making the dry-time much shorter. Sometimes people will use the possession wring-out to mean complete something, remove adjectives unnecessary ecxess, or something like that - it's a pre-process that will procure rid of waste and unneeded stuff within the final product, but I wouldn't use this in regard to wiring (unless river has gotten into my electrical system, as it did in my car's electric wiring one time - that required some SERIOUS wringing and drying).
