Technical Parameters

I. Features

1. The device has protection functions such as overvoltage, overcurrent, zero start, system detuning (flashover), etc. The overvoltage and overcurrent protection value can be set according to the user's needs, and the flashover protection action can be recorded when the sample flashovers The value of flashover voltage for test analysis.

2. The weight of the whole device is very light, which is easy to use on site.

3. The device has three working modes, which are convenient for users to choose flexibly according to the on-site situation and improve the test speed.

The working modes are: automatic mode, manual mode, automatic tuning manual boost mode.

4. Data can be stored and printed in different places. The stored data number is a number, which is convenient for users to identify and find.

5. When the device automatically sweeps the frequency, the starting point of the frequency can be set arbitrarily within the specified range, and the sweep direction can be selected upwards or downwards. At the same time, the large LCD screen displays the scanning curve, which is convenient for the user to intuitively understand whether the resonance point is found.

6. The DSP platform technology is adopted, which can easily add or remove functions and upgrades according to user needs, and also makes the man-machine exchange interface more user-friendly.
