Product Parameters
1, measurement channel: independent 2 channels.
2. The capacitance range of the test product is 6pF~250μF.
3, detection sensitivity: 0.1pC.
4, sampling accuracy: 12bit; Sampling rate: 20M/S.
5. Display working mode
(1) Display method: ellipse -- sine -- straight line
(2) Trigger synchronization mode: internal and external trigger mode, internal trigger for the instrument power synchronous trigger, 50Hz;
The external trigger is the working frequency of the synchronous test power supply, any frequency within 50~400Hz.
(3) External trigger synchronization signal input voltage: 10~200V, input power <1 volt-ampere.
(4) Signal phase determination: the ellipse is displayed in polar coordinate mode, and the sine is displayed in sine wave mode. The starting point of the display graph is the zero point of the test power supply, and the length of the display graph is a period of the test power supply. Under the external trigger synchronization mode, the system accurately and truly displays the period and phase of the test power supply.
6, time window: the phase size is arbitrarily selected, can dynamically enlarge the display time window, two time Windows can be opened separately or simultaneously.
7, filter frequency band: 3dB low frequency fL 10, 20, 40kHz file, 3dB high frequency fH 80, 200, 300kHz file, fL and fH can be flexibly composed of various filter passbands.
8, signal amplifier:
(1) Gain adjustment: divided gain coarse and gain fine adjustment, gain coarse adjustment is divided into 5 grades, gain difference between grades 20dB (10 times), error ± 1dB adjustment; Gain fine-tuning range >20dB.
(2) Asymmetry of positive and negative polarity response of amplifier: <1dB.
9, local discharge signal measurement: can be measured in continuous, amplified display working mode, error ±5% (in full scale).
10, with data storage, playback function. With printing function, generate standard test report.
11, working environment temperature: -10 ~ 45ºC, relative humidity: ≤95%.
12, power supply AC220V; Frequency 50Hz; Power 300W.
