How To Read Ethernet Cable Tester

An Ethernet cable tester is a device that helps you troubleshoot and check the status of Ethernet cables used for networking purposes. It detects any faults or issues with the cables and provides information about the continuity of the wires, presence of shorts, and the overall connection status. Here's how to read an Ethernet cable tester:

1. Check the LED lights

Most Ethernet cable testers feature LED lights that provide visual indications of connection status. The status lights indicate whether the cable is properly connected, the wiring is correct, and whether there is a break in the cable. The LED lights typically come in pairs or sets, and each one represents a specific function.

2. Follow the color code

Ethernet cables need to be wired based on a specific color code standard, such as T568A or T568B. Check if the Ethernet cable tester is programmed to follow the correct color code. The tester will display a green light if the wiring is correct, and a red light if the wiring is incorrect.

3. Check the pairings

Ethernet cables comprise of four twisted pairs of wires. The Ethernet cable tester can determine if the pairs are correctly paired or mismatched. Each pair has a specific color code, and the tester will display a green light if the pairs are correctly paired and a red light if there is a mismatch.

4. Continuity testing

The Ethernet cable tester can test for continuity and check if all the wires in the cable are connected from one end to the other. This type of testing is ideal for checking the integrity of the cable and ensuring that there is a proper connection.

5. Short circuit testing

Short circuit testing is another feature that comes with Ethernet cable testers. This function helps you determine if there are any short circuits in the cable. The tester will show a red light if there is a short circuit and a green light if there is no short circuit.

6. Check the display screen

Most Ethernet cable testers come with a display screen that displays the test results. The display screen provides additional information, such as resistance, length of cable, and pairing of wires in the cable. This information can help you determine the health of the cable and diagnose any problems.

In conclusion, reading an Ethernet cable tester is easy if you follow the steps mentioned above. Testing Ethernet cables is essential for ensuring the integrity of network connections, and Ethernet cable testers make the process quick and easy. By following the standard color code and using the Ethernet cable tester properly, you can maintain optimal network performance.
