KD-219 communication cable fault automatic comprehensive tester is a high-tech product successfully developed by modern microelectronic technology. It has two test methods, pulse reflection and intelligent bridge, which are suitable for measuring the precise position of the local lead-covered cable, all-plastic cable, the broken line, the mixed line, the ground air, poor insulation, poor contact and other faults. It is an effective tool to shorten the time of fault finding, improve work efficiency and reduce the labor intensity of line maintenance personnel. Line inspection and repair personnel can also use it for line engineering acceptance and check cable electrical characteristics.

1, pulse reflection test method:
Maximum range: 8km, you can choose the appropriate range according to the cable length.
Test blind area: 0m
Test accuracy: 1m when the range is less than 2km; 8m when the range is greater than 2km
Pulse width: 80ns-10μs automatic adjustment
