1. Multifunctional cable detector, suitable for detecting short circuit and open circuit faults of cable lines, and direction of underground cable fault pipelines. 2. The digitally encoded signal ensures that it can be clearly received by the receiver and avoids false display caused by interference fields (such as electronic fluorescent lamp ballasts or inverters). 3. The transmitter has a self-checking function, and the sensitivity of the receiver can be adjusted automatically or manually, which is stable and reliable. 4. The receiver has an automatic frequency scanning function, and the transmitter and receiver have a mute function, which can be used in a quiet testing environment such as a hospital. 5. Widely used in communication cable construction, power cable construction, pipeline construction and communication cable maintenance work with power supply circuits and electric heating circuits.
