If you set your multimeter to read ohms and the lead tips are not touching that is an open reading. When you touch the lead tips together, that reading is a short. I have a video that explains how to use a multimeter to check resistance/continuity. Here's the link: th-cam.com/video/9H-uMSGHFXM/w-d-xo.html
Thank you for the tutorial. This test is to see if you coax cable is defective or not able to carry a signal. Is there a method for testing for a single to see if the coax wire is working before plugging it into the modem? Like you would check for current in and extension cord or wall outlet?
A multimeter will help you identify one cable run from another or find a cut/severely damaged cable. If the cable run is visible, you can look for hard bends, look for high voltage a cable (home AC wiring) run parallel with the coax. With a device connected you can shake any connectors to see if they interrupt the signal. To test the signal strength you'll need a device designed for that purpose.
Great video, i was wondering if there is a way to use a multi meter to check if any of the staples the installer used to secure the cable had pierced the coax and were affecting my signal quality. thanks in advance.
I can't think of a practical way to test the staples with a multimeter. If you are concerned about the quality of the installation, the best thing to do is to visually inspect the cable. You should be able to see if they drove a staple through the coax, crushed it or put kinks/hard bends in it. A multimeter is good to check for a cut, severely crushed cable or to identify a specific cable. Checking for good signal requires more sophisticated test equipment.
Know How Now Thanks for replying so quickly. I thought maybe there would be a way to use the meter to go down the line one by one and check to see if there was any current or signal in any of the Staples.
Thank you so much for this. I want to check a coaxial outlet in my wall to see if it has a signal (to use for a cable modem). I don’t want to call out a technician. Will a multimeter do the job? Thanks again.
Hi Justin, a multimeter can't be used to check the signal. If you only have one coaxial outlet that is not working, the best you can do is to follow the cable back from the outlet to the next connection. Disconnect it at the next connection and use your modem to check for signal at that location. Work your way back to where it enters the building until you have a signal. Look for damaged cable ends or damaged coax.
@@Know-How-Now The video was great, that's why this troll is posting this comment. Trolls are strange. Posting nasty comments is what Jorge Pulido does for fun. Can you imagine?

Thanks! I wanted a quick way to trace a coax cable back to my splitter and this video was perfect!
You are welcome, Dane. Thanks for watching the video and taking the time to comment.
This video made me happy. I've watched it over 6 times now and I keep learning
Thanks for taking the time to comment. It's great to hear that you have learned something new from the video.
Props for the old Micronta! I feel like I'm 15 again!
Great video too! You can tell when someone enjoys this stuff.
I bought it at Radio Shack in the early 1990's. I used it for my work every day for a few years until I got a Fluke.
Excellent presentation; Very helpful. Thank you for sharing.

At about 5:45 into the video you show testing for a longer coax cable and state "make sure you read an open", what does that mean?
If you set your multimeter to read ohms and the lead tips are not touching that is an open reading. When you touch the lead tips together, that reading is a short.

Awesome video. I wish you all the best.

How did you do it to find out if a Wire is damaged by a staple ?
thanks only one i found that i can follow ..
You're welcome
very well communicated message for instruction.
Thanks for the compliment, Buck Wheat. Have a great day.
I love this. Learned a lot!
Thanks for taking the time to comment, it's always nice to hear the videos are helpful.
Very informative video. Thank you.
You are welcome thanks for watching the videos. I'm having fun making them.

Awesome. Will do. Your response is greatly appreciated. Take care.
You are welcome. Good luck with your "detective work".
Cool 2102 +
Thanks. Returned the favor.
Christopher Walken. called. and. Wants. His voice. Back!!!😂😂🤣
Lol, usually people think I sound like Jodie Foster.
Boring
If you were making your first video (your channel has no videos uploaded) on this topic, how would you make it not boring?
