產品介紹
MEWOI3100B+鉗形接地電阻儀是我公司技術研發團隊對科技品質的卓越追求，通過不斷創新完善，對老款產品的徹底陞級。其效能主要體現在：突破開機長時間自檢等待，開機立即進入測試。突破繼電器自檢管道，採用先進的算灋及數位集成處理科技。突破老款產品笨重的問題，更加符合手持儀錶的特性。全新外觀設計，面板6鍵操作，效能直通。新增了聲光報警功能，“嘟--嘟--嘟--”報警聲。新增了干擾訊號識別訓示功能，“嘟--嘟--嘟--”聲提示。測量範圍新增到0.01Ω-200Ω。存儲數據99組，功耗更低，最大啟動、工作電流小於50mA。廣泛應用於電力、電信、氣象、油田、建築及工業電氣設備等的接地電阻量測、回路電阻量測。在量測有回路的接地系統時，不需斷開接地引下線，不需輔助接地極，安全快速。能量測出用傳統方法無法量測的接地故障，能應用於傳統方法無法量測的場合，因為ETCR系列鉗形接地電阻儀量測的是接地體電阻和接地引線電阻的綜合值。 |
