The ET835PRO offers various functions for testing network cables (RJ45, CAT5, CAT6, CAT7, CAT8 UTP/STP).

4.1.1 Cable Length Measurement

This function measures the length of network, phone, and coaxial cables.

1. Select LENGTH from the main menu.
2. Connect one end of the cable to the main unit's TEST/SCAN/QC/ID interface.
3. For accurate readings, ensure the other end of the cable is not connected to any active device.
4. The device will display the cable length in meters or feet.
5. Calibration: For precise length measurements, especially for different cable types, calibration is recommended. Connect a known length of cable (e.g., 5 meters) and follow the on-screen calibration prompts in the LENGTH menu.
