KB12 Long Cable Testing - Knowledge Base article #12.
This article describes how to test very long cables. The standard autotest is supported by the TestPro up to 600m. There is also a special test mode for cables from 500m to 1000m in length. These situations are becoming more common with the growth in Cat 3 IoT and low speed building automation applications.
