| Characteristics: |
- Full automatic, high accurate computer-aided measurement in the frequency range between 10 to 400 Hz
- Integrated digital signal processor (DSP) permits the evaluation of the data within each cycle of the applied AC test voltage (20 ms)
- Status of frequency selective measurements on FFT-basis which reduces the interference by harmonics superimposed to the test voltage
- Comprehensive information also in magnitude and frequency of the test voltage
- Graphic user interface displaying the spectrum and the time dependent trend of the dissipation factor and capacitance as well as the time
function of the test voltage
- Integrated hard disk and floppy disk are used for data storage and file transfer
