What is a Cable Tester?
A cable tester is a hand held electronic device. It is used to verify electrical connections in a cable network. Signal strength, particularly in a computer networks, is crucial for data transmission.
A cable tester can come in one of many shapes & sizes, and may have multiple functions. A hand held battery-powered tester checks for insulation losses and crossed wiring, and is generally easy to use. Most testers are designed with two parts – the tester itself and a remote. Testers typically have different testing ports to test today’s most popular media including ports for RJ-45, RJ-11, USB and BNC.
When to Use a Cable Tester:
Once you are ready to check if a cable is set up properly to achieve a strong connection between source and destination. That time is, typically, after installation / set up is complete. It is good practice to test the system once all components are connected in order to assure the job has been done properly. If the test shows connectivity troubleshoots, you can address the issue(s) and retest.
Connection between server and computer(s) is weak
Outside interference causing data loss or decreased signal strength
How to use a Cable Tester:
1. Select the cable to be tested and make sure it is not plugged to any electrical power and free of any packaging or tangled with other cables, to prevent false reading.
2. Visually inspect the cable for damage. If cable is broken or torn it should be replaced.
3. Plug the network cable into the appropriate port on the cable tester, and then connect the other end of the cable to the remote.
4. Switch the tester on to test your cable. The tester will show results, and if applicable, will indicate what the potential problem is.
