What do test points help a technician diagnose without impacting?

Test points are specific locations within a system or circuit where a technician can connect measuring devices to assess the functionality and performance of the system. The significance of test points lies in their ability to provide insights into the system's operation while maintaining normal service. By utilizing test points, technicians can evaluate the system for various parameters without causing any service interruption to the users or the overall workings of the device.

This capability is crucial in environments where uptime is essential, and any disruption could lead to significant consequences, such as in telecommunications or network services. Therefore, the use of test points allows for diagnostics to occur seamlessly, ensuring that users remain unaffected during the assessment process.
