It is a new current ratio standard after the zero flux current transformer, two stage current transformer and current comparator.
它是继零磁通电流互感器、双级电流互感器和电流比较仪之后的又一种新型的电流比例标准。

Move with the X axis micrometric movement the sharp shadow, till the digital comparator red light is on the zero right position.
微调移动X 轴接近“十”字比较尺，直到数字比较器的指示灯在零点右边变亮。

Through adding a zero-crossing comparator and optimizing the inverter switching logic, this method which is based on the traditional two-state hysteresis control can achieve three-state outputs.
