設備功率管IGBT測量方法，1、2、3腳分別是G、C、E，用萬用表10K歐姆檔測量，黑表筆接第2腳，紅表筆接第3腳。用手觸摸1、2腳導通，觸摸1、3腳截止，說明這個功率管是完好的。

How to measure the IGBT？

Measurement method for IGBT of equipment power transistor, pins 1, 2, and 3 are G, C, and E respectively, measured with a multimeter in 10K ohm range, with the black probe connected to pin 2 and the red probe connected to pin 3. Touch pins 1 and 2 with your hand to turn on, and touch pins 1 and 3 to turn off, indicating that this power transistor is intact.
