Features

??With the protection function of over-voltage, over-current, zero-start, system detune (flashover). Over-voltage, over-current protection value can be set accordingly to user’s need. Flashover protection starts?when flashover and the flashover voltage value?will be recorded?for testing analysis.

??The unit piece of the device is light, suitable?for field use.

?There are three kinds of working mode for user choosing according to on-site condition.

?Automatic mode, Manual mode, Automatic tuning manual boosting?mode.?

?Data can be stored, and the stored?data No.?are figures which is easy for identification and searching.

??Frequency starting point can be set in the specified scope when the device sweep frequency automatically, sweep frequency direction can be selected?upward or downward, meanwhile LCD displays the scanning curve, which is convenient to know if the resonant point?found?or not intuitively.

???With DSP technology, which can increase or decrease functions and updated accordingly to the user’s need, it also makes the human-machine interface more friendly.
