The transmitted signal is digitally encoded to ensure that the receiver receives the signal clearly and avoids false readings caused by interference fields.Determine the route of cables wires water and gas pipelines laid on the walls and underground. Detect interruptions or short-circuit faults in cables and wires laying on walls and underground. Pay attention to fuses and safety circuits. Pay attention to hidden sockets and junction boxes. Look for breaks and short circuits in the electric heating circuit under the floor.The transmitter has an AC/DC voltage measurement function which can linearly measure AC and DC voltages of 12-400 V. The transmitter can display the set transmit power level transmit code battery power information the measured value and type of external voltage and the symbol of external high voltage alarm which can also be displayed on the receiver.The screen of the receiver can display the power of the transmitter the code sent the energy of the transmitter and its own battery the detected AC voltage signal and the mains voltage warning symbol. The receiver has an automatic frequency scanning function. The receiver can be turned off automatically. The LCD screen of the receiver is backlit suitable for low light applications.This instrument is widely used in the manufacture of communication cables power cables pipelines communication cables with power circuits and electric heating tubes. It is an essential tool for building maintenance personnel.Electricians often need to track cables or wiring systems and often need to determine whether safety equipment is connected to a specific circuit or identify and track metal pipes heating pipes or underground cables. This cable detector can help such users.characteristic:The transmitted signal is digitally encoded to ensure that the receiver receives the signal clearly and avoids false readings caused by interference fields.This instrument is widely used in the manufacture of communication cables power cables pipelines communication cables with power circuits and electric heating tubes.
