8761精密線材測試儀採用四線式量測技術
直接連接至待測線束之兩端進行測量，避免整體接線所產生的誤差，使量測阻抗更精密可達到1mΩ。
8761一機提供四線式導通阻抗、斷短路測試、AC/DC安規耐壓與絕緣測試，以及元件測試功能
導通阻抗測試目的
測試線材連接器接點是否有接觸阻抗性的問題
斷短路測試目的
確保線材連接器接點是否有無功能上的問題，MICROTEST線材測試儀支援斷短路端點判定與學習迴路
在安規測試單元提供AC/DC耐壓以及絕緣阻抗測試功能
對線材連接器施加一個穩定高電壓進行測量，目的確保待測物之耐壓能力與絕緣品質，確保線材連接器之迴路接點是否符合絕緣性與耐高壓要求
線材/連接器生產製程中會造成那些安規方面的品質不良？
絕緣不良
電路與電路之間或與其他線路之絕緣阻抗小於產品標準品質規範
耐壓不良
電路之高壓絕緣阻抗小於產品標準品質規範或因絕緣性太差造成漏電流狀況
安規檢測項目中兩大重要指標
絕緣阻抗
測試結果以絕緣阻抗值判定，絕緣阻抗是反應絕緣材料性能一項重要電氣參數，絕緣阻抗不良可能會發生高壓下待測物被擊穿或漏電流
電弧偵測
許多車用或軍工應用的精密產品是不容許高壓下出現電弧的現象
