Technical data
- Measurement channels
- Independent two-channel / four-channel
- Test-object capacitance
- 6pF～250μF
- Measurement range
- 0.1pC～10000nC
- Detection sensitivity
- 0.01pC
- Sampling accuracy
- 12bit
- Sampling rate
- 20M／S
- Display method
- Ellipse, sine wave, straight line
- Trigger synchronization mode
- Internal trigger synchronized to the instrument power supply, 50Hz; external trigger synchronized to the operating frequency of the test power supply, any frequency within 50～400Hz
- External trigger sync signal input voltage
- 10～200V, input power＜1VA
- Signal phase determination
- Ellipse display uses polar-coordinate mode; sine display uses sine-wave mode. The displayed graphic starts at the zero point of the test power supply and has a length of one cycle of the test power supply
- Time window
- The phase can be selected freely; the time window can be dynamically magnified; the two time windows can be enabled separately or simultaneously
- Filter band
- 3dB low-frequency end: 20, 40, 60, 80kHz or OFF (9kHz); high-frequency end: 100, 200, 300, 400kHz or OFF (1MHz)
- Digital filtering
- Freely selectable from 10kHz～1MHz
- Gain adjustment
- 5 coarse-gain steps, with a 20dB gain difference between steps; fine-gain adjustment range ＞20dB
- Positive/negative polarity response asymmetry of amplifier
- ＜1dB
- Partial-discharge signal measurement
- Error ±5% (of full scale)
- Display plots
- 2D and 3D
- Operating temperature
- -10～45℃
- Relative humidity
- ≤95%
- Power supply
- AC220V；50Hz；power 100W (using a 300W industrial-grade power supply)
- Dimensions
- 440mm (width), 385mm (depth), 315mm (height)
