Nickname：cable fault detector，cable locator，Cable Fault Locator
Feature:
Fully Featured
It can test faults safely, rapidly and accurately ; This Tester uses low-voltage pulse method and high-voltage pulse flash-over method to detect a variety of cable faults, especially for flash-over of cable, it can be used directly without burning through cables . If equipped acoustic tester, the exact location of the fault can be accurately measured;
High precision
The instrument uses a high speed data sampling method ,The sampling rate of A/D can be 100MHz, which made the read resolution of this machine is 1 meter, and the blind spot detection scope is 1m.；
High intelligence
Test results are automatically displayed on the large LCD display with waveform and data; which made the fault spot easy to be detected. And it owns Chinese menu with operation functions, so you don't need the training of the operating personnel;
The waveform and data can be stored and tuned out;
waveform and data will still be stored even when it is turned off because of the function of the non-volatile devices.
it can show the dual trace;
it can compare the fault waveform with normal waveform, which is conductive to further determine the fault;
It can extended the proportional of the waveform;
If the waveform proportion changed, the accurate testing can be achieved ;
The position of the double cursor can be changed as you like, it can show the direct distance or the relative distance of the fault point and the tested point ;
It can modify the transmission speed with different tested-cable;
The small size makes it portable and the built-in rechargeable battery makes it easy to carry and use.
