| 钳表的使用 |
钳表是一种用于测量正在运行的电气线路的电流大小的仪表，可在不断电的情况下测量电流。
1．结构及原理
钳表实质上是由一只电流互感器、钳形扳手和一只整流式磁电系有反作用力仪表所组成。
2．使用方法
（1）测量前要机械调零
（2）选择合适的量程，先选大，后选小量程或看铭牌值估算。
（3）当使用最小量程测量，其读数还不明显时，可将被测导线绕几匝，匝数要以钳口中央的匝数为准，则读数＝指示值×量程 / 满偏×匝数
（4）测量时，应使被测导线处在钳口的中央，并使钳口闭合紧密，以减少误差。
（5）测量完毕，要将转换开关放在最在量程处。
3．注意事项
（1）被测线路的电压要低于钳表的额定电压。
（2）测高压线路的电流时，要戴绝缘手套，穿绝缘鞋，站在绝缘垫上。
（3）钳口要闭合紧密不能带电换量程。
