What is one method for testing limited-energy cabling?

Using a cable certifier or tester to check for continuity and performance is a recognized and effective method for testing limited-energy cabling. This approach ensures that the cabling meets specific performance standards and is capable of handling the intended data and power transmission. A cable certifier can provide detailed information about the cabling’s electrical characteristics, including resistance, capacitance, and transmission quality, thereby helping to verify that the installation complies with relevant codes and standards.

In contrast, a visual inspection alone lacks the ability to identify hidden issues that might affect cabling performance, such as internal damage or improper connections. While using a multimeter for voltage checks can provide useful information about power levels, it does not assess the cable's overall performance or data transmission capabilities. Testing with a smartphone app is also limited, as many of these applications lack the comprehensive testing features necessary for thorough analysis that a dedicated cable certifier possesses.
