1.整体电路的检测原则电路的故障,一般是断路或短路(或几条线烧损短路粘在一起)。当电动自行车某一电路工作不正常时,首先应分析电路的性质和特点,确定检测点,然后测试其电流和电压,将故障范围锁定后,再沿线路逐级查找。2.直流电流的检测直流电流的检测有直接测量和间接测量两
1. The detection principle of the whole circuit Circuit failure, usually open circuit or short circuit (or a few lines burning short circuit stick together). When a certain electric bicycle circuit is not working properly, we should first analyze the nature and characteristics of the circuit to determine the test point, and then test the current and voltage, the fault range locked, and then step by step along the line to find. 2. DC current detection DC current detection has direct measurement and indirect measurement of two
