Features 1) DAGC (Digital Gain Automatic Control) system The gain can be modified digitally. Eliminate the waveform distortion caused by the potntiometer knob. It can also do pure linear adjustment, which is convenient for manual testing. 2) Digital waveform automatic recognition technology,Automatically recognize the waveform that are difficult for human to determine. 3)Using ARM CPU with FPGA technology, can quickly perform various complex operations and determine fault waveform accurately. 4) Waveform comparison function, it is convenient to compare the test waveform of the fault cable and the normal cable, and clearly find the fault point location. 5) Large-screen LCD color display, humanization design of the interface menu, fast digital press button, easy for users to operate. 6) High-power lithium battery, which can be used for up to ten hours (with specialized power charger). 7) With data interface to support customers upgrade the system remotely.
