表的主要技術性能:

1、測量范圍、測量電流、準確度、靈敏度、分辨力等應全面滿足國家標準 GB/T3048.2 《電線電纜電性能試驗方法 第 2 部分:金屬材料電阻率試驗》 及 GB/T3048.4 《電線電纜電性能試驗方法 第 4 部分:導體直流電阻試驗》 中對電阻測試設備的各項技術要求。

2.為了方便用戶操作,在儀表的附加功能中添置了 GB/T3048.2 及 GB/T3048.4 推薦的一些特殊功能及測量方法,如反向電流測量、倍率電流測量、熱電勢平衡、導線溫度校正等功能。

3.可以適應不同規格電線電纜生產廠的需要。儀表的技術指標和功能設置以適應標準的要求為主,以滿足用戶的需要為主,做到既是充分的又是必要的,力爭實現較高的性能價格比。

PC36C直流電阻測試儀工作原理:

本儀器是由5 1/2位,具有0.1μV靈敏度的數字電壓表和一個精密恒流源組成,由精密恒流源流出的電流I0在被測電阻RX產生一電壓降,同時用5 1/2位數字電壓表去測試這個電壓降,其測量結果用電阻值反應出來。因此該表可測試0.001μΩ~200Ω的電阻。
