      本儀表與傳統手搖式地阻儀相比，具有以下特點:
      >應用了DC/AC變換技術，集三端鈕、四端鈕量方式為一體，使用電源可交、直流兩用。
      >采用鎖相同步跟蹤檢波方式，及開關電容濾波器，使抗干擾能力極強。
      >摒棄了傳統的人工手搖式發電方式，不需人力做功。
      >不需人工調節平衡，一目了然的面板觸摸鍵操作，數字顯示測量十分方便和迅速，消除了指針式儀表的視覺誤差。
      >允許的輔助接地電阻阻值很大，更好的保證了測量精度，分辨率高。
      >除測試接地電(dian)阻外，還可以測試低(di)壓電(dian)阻導體(ti)電(dian)組(zu)值。土壤電(dian)組(zu)率以及(ji)交流地電(dian)壓。
