如何用万能表测量非凡蓄电池

可将万用表拨至直流挡位上，两表笔分别跨接在蓄电瓶两电极上，此时若电瓶显示出正常电压值，则证明红色表笔所触的电极为电瓶正电极．而黑表笔处则为负电极。有时测得电瓶无正常电压存在，则可测量电瓶的弱微存电量加以判断。当两表笔碰触电瓶电极后，表针若向右微微晃动，即证明红笔处为电瓶正电极．黑表笔处为负电极。但如果万用表指针向左晃动(表针反打)，则证明红笔所触及处为电瓶的负电极。

You can set the multimeter to the DC position and connect the two probes across the two electrodes of the battery. If the battery displays a normal voltage value at this time, it proves that the electrode touched by the red probe is the positive electrode of the battery, while the electrode touched by the black probe is the negative electrode. Sometimes, if there is no normal voltage present in the battery, the weak micro storage capacity of the battery can be measured to determine. When the two probes touch the battery electrode, if the probe shakes slightly to the right, it proves that the red probe is the positive electrode of the battery and the black probe is the negative electrode. But if the pointer of the multimeter shakes to the left (the pointer is reversed), it proves that the red pen touches the negative electrode of the battery.
