The cable identification instrument is mainly composed of the following six parts: 1. Signal transmitter: output a high-frequency electromagnetic signal of a certain power, and apply it to the pre-identified power failure or live cable, and generate a constant current on this cable. 2. Signal receiver: The cable identification instrument detected by the coupling clamp is mainly composed of the following six parts. 1. Signal transmitter: It outputs a high-frequency electromagnetic signal of a certain power, and applies it to the pre-identified power failure or live cable. A constant current is generated on it. 2. Signal receiver: The signal detected by the coupling clamp is displayed in the form of grating length, number size and buzzer, and the operator makes a judgment based on the strength of the received signal.
3. Coupling clamp: used to transmit and receive electromagnetic signals (the electrical properties of the transmitting clamp and the receiving clamp are different, do not use them interchangeably). 4. Charger: used to charge the signal transmitter and receiver. 5. Direct connection signal line: It is a red and black double-clamped line, which is used for direct connection identification of power failure cables.
6. Coupling clamp connection: used to connect the coupling clamp to the signal transmitter and receiver.
