对于直流电流测量﹐在电流通道串联一电流分流器﹐将电流转换成直流电压信号。
For DC current measurement, a current shunt is place in series in the current path and convert the current to a DC voltage signal.
加上出色的直流电阻稳定，分流可用于直接测量电流通过他们的全部带宽。
Combined with excellent dc resistance stability, the shunts can be used to directly measure current through their full bandwidth.
J0409型灵敏电流计适用于中学、中专等实验室测量直流电路中微小电流和微小电势差。
Sensitive Galvanometer, Model J0409, is suitable for the laboratories of middle schools and polytechnic schools to measure small electric current and electric potential difference.
