Description
The CRT is mainly used for cable fault location, cable identification, cable path and depth measurement, can quickly and effectively determine the direction and depth of underground metal pipelines. With signal strength indication, left and right arrow indication, compass direction indication,the maximum depth of the detection pipeline can be up to 20 meters.
The CRT consists of a transmitter and a receiver.
This machine is a multi-frequency high-power transmitter, with constant power output, automatically matching the external load, to ensure that the machine works in the best state. With ohmmeter function, it can detect external voltage and test continuous loop resistance, which can help to determine the nature of the fault.
The receiver uses a 3.5-inch true color LCD display, displaying signal strength figures, amplitude light bars, compass pointing, left Right arrow pointing, current direction indication, used to indicate the strength of the signal, optical cable location, fault detection, optical cable identification, depth measurement.
