Semiconductor tube characteristics grapher model: qt2
The qt2 semiconductor characterization grapher measures low-frequency direct flow parameters for two and three tubes, and z large-assembled electrical currents exceed 50a to meet the test for devices below 500va. This machine is equipped with a high-pressure detector device that allows two or three tubes below 5kv to be tested for penetration and reverse leakage computers. Its test current z can be as sensitive as 0. 5 μa/div。
