本機專門試驗插頭片與導體之接合強度及導體線之抗突拉強度。試 法是將插頭片固定于插座內(nèi)，導線尾端連結沖擊錘桿并連結到電線 通斷指示燈的插座內(nèi)，設定好試驗次數(shù)及突拉高度后即可測試突拉 ，之后吊上砝碼進行扭轉試驗及接地電流試驗。本機可做突拉試驗 、扭轉試驗、荷重試驗及接地電流試驗。 
This tester is specialized in testing abrupt / rotary pull strength between the blades and conductor。Fix the blades to the plug fixture and tie the cord to the grip with stripped conductors outside on which the crocodile clips clamp。Afterward，hang the weight assembly onto the grip hook to perform the above test。It can also execute the current test independently。
