Feature: 1. Multifunctional cable detector, suitable for detecting short circuit and open circuit faults of cable lines, and the direction of underground cable fault pipelines. 2. Digitally coded signal ensures that it can be clearly received by the receiver and avoids any 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. Receiver has an automatic frequency sweep function, and both the transmitter and the receiver have a mute function, which can be used in a quiet test environment such as a hospital. 5. Widely used in communication cable construction, power cable construction, building pipeline construction, and maintenance work of communication cables with electric power supply circuits and electric heating circuits.
