The track circuit fault diagnosis instrument is a fully integrated and highly reliable fault diagnosis instrument for track circuits. It has the characteristics of small light, easy to carry, easy to use, stable performance, strong anti 50Hz interference ability and quick search fault. It is an ideal tool for finding fault of track circuit. It is not only suitable for the non electrified section, but also for the 25Hz phase sensitive track circuit of electrified section and the test of various shift frequency track circuits.
