This device is often used in network installations, telecommunication systems, electrical installations and other similar areas. The MS6812 model has a toning feature that is widely used to determine the correct connection of cables. Toning is the process of generating a specific signal in the cables and monitoring the passage of this signal through the cables. In this way, cable fault can be detected and the correct connection of cables can be ensured.
