Power line whether breakover, whether with plug bad contact.
电源线是否导通，是否与插座接触不良。

Besides, the test board which is used for testing the semiconductor arrester's breakover voltage is designed.
另外，对于半导体放电管转折电压的测试，设计出相应的转折电压测试板，并完成调试。

This error voltage serves as is controls the electric charge pump breakover resistance (to call that it controls resistance pressure), then obtained a stable output voltage.
