The 3.7V function is complete to test fail-safe, fast and accurate. The instrument uses low-voltage pulse method and high-voltage flashover method to detect various cable faults, especially for cable flashover and high-resistance faults, which can be directly tested without burning through. If equipped with an acoustic point measuring device, it can accurately determine the precise location of the fault.
