福瑞泰 FT286 钳形万用表使用说明一、设备介绍
这是一台福瑞泰（FUKET FT286）数字钳形万用表，是汽修、电工领域的常用工具。它兼具钳形电流表和数字万用表的双重功能，既可以像普通万用表一样测量电压、电阻、通断，也可以通过钳口直接夹住导线，测量交流电流，无需断开电路。面板按键与接口详解
二、基础使用方法
1. 测量直流电压（如电瓶电压、传感器供电）
用途：测电瓶是否亏电、线路是否有电、传感器供电是否正常。2. 测量交流电流（钳形表核心功能）
用途：测大灯、风扇、油泵等负载的工作电流，判断是否过载。3. 测量电阻 / 通断（蜂鸣档）
三、安全注意事项
表笔插孔与档位必须对应：严禁用电流档 / 电阻档去测电压，会瞬间烧毁仪表。高压测量时，先接黑表笔，再接红表笔；测量结束先取红表笔，再取黑表笔。钳形表测量电流时，钳口必须完全闭合，且只能夹一根导线。测量带电线路时，不要用手触碰表笔金属部分，防止触电。不使用时，将旋钮打到 OFF 档，长期不用取出电池。
