西瑪可控硅晶閘管R175SH24 R0736LS24J
將萬用表撥至R×1檔，測量任意兩腳間的電阻，僅當黑表筆接G極，紅表筆接K極時，電阻呈低阻值，對其它情況電阻值均為無窮大。由此可迅速判定G、K極，剩下的就是A極。
2．檢查觸發能力
如圖2(a)所示，首先將表Ⅰ的黑表筆接A極，紅表筆接K極，電阻為無窮大；然后用黑表筆尖也同時接觸G極，加上正向觸發信號，表針向右偏轉到低阻值即表明GTO已經導通；后脫開G極，只要GTO維持通態，就說明被測管具有觸發能力。
3．檢查關斷能力
現采用雙表法檢查GTO的關斷能力，如圖2(b)所示，表Ⅰ的檔位及接法保持不變。將表Ⅱ撥于R×10檔，紅表筆接G極，黑表筆接K極，施以負向觸發信號，如果表Ⅰ的指針向左擺到無窮大位置，證明GTO具有關斷能力。
4．估測關斷增益βoff
進行到第3步時，先不接入表Ⅱ，記下在GTO導通時表Ⅰ的正向偏轉格數n1；再接上表Ⅱ強迫GTO關斷，記下表Ⅱ的正向偏轉格數n2。根據讀取電流法按下式估算關斷增益：
βoff=IATM/IGM≈IAT/IG=K1n1/K2n2
式中K1—表Ⅰ在R×1檔的電流比例系數；
K2—表Ⅱ在R×10檔的電流比例系數。
