1. Independent two-channel digital partial discharge measurement, synchronous sampling, processing and display;
2. Internal and external synchronization can be selected at will, and it has the function of zero mark indication and phase resolution;
3. Display mode: free choice of three display modes: ellipse, straight line and sine;
4. Analysis of single discharge pulse waveform in order to determine the nature of discharge;
5. Save the test data and waveforms at any time, and redisplay and analyze the saved test records in the past;
6. Gain range: each channel can be adjusted independently, and the waveform display can be smoothly adjusted at any time without affecting the measurement results;
7. A single capture and a detailed analysis of special or random waveforms can be performed;
8. Anti-static interference function, which can remove the interference signal with fixed phase;
9. The anti-interference function of relevant filtering technology can effectively remove random interference that is not synchronized with the power supply;
10. The band-pass filter adopts analog and digital hybrid filtering technology, and the bandwidth can be combined arbitrarily, effectively suppressing various interferences;
