2. Main Features
Data of current and voltage are obtained directly through the sampling of high-pressure side and it is true and accurate.
Over-voltage protection.
Over-current protection.
High-voltage output protection resistor design in the HV TANK and it is no need to additional outside resistor.
Closed-loop negative feedback control circuit of high and low voltage.
3. How to choose the suitable products for test
Please make sure that the capacitance of test products is below the instrument rated capacitance . The waveform will be influence if the capacitance of test products is too small and the instrument can not normally output when it below 0.05µF. 0.05µF capacitor in parallel to auxiliary output . Below is capacitance of some instrument for your reference .
