This device can be used to locate underground cable paths (with or without electricity) as well as to search for faults in buried cables. Can complete tasks that were previously only possible with several sets of instruments. Specially suitable for fast and accurate positioning of cable to ground insulation and open/short circuit faults, as well as online or offline underground cable path search and depth measurement.

When the instrument is in use, the internal battery can be connected to an AC power source for float charging. But during high-voltage flashover testing, it is necessary to disconnect from the external AC power supply. When the instrument needs to exit the testing state and shut down, the operating procedure should be followedThe 'Exit' button gradually returns to the desktop system, and then shuts down the computer. Do not directly turn off the 'power switch'. The LCD displays the direction and distance of the fault. The fault point is indicated by an arrow at the front and back, and the distance barcode of the fault point is displayed intuitively. The more barcodes there are, the closer it is to the fault point. The error is measured in centimeters.
