电压监测仪的静电放电抗扰度不合格整改

Rectification of Voltage Monitor for Electrostatic Discharge Immunity Test

电压监测仪的静电放电抗扰度试验结果不合格,通过分析试验中出现的液晶屏没有显示和黑屏等现象,采取了增加滤波电容、减小耦合面积等整改措施,整改后电压监测仪通过了静电放电抗扰度试验。

The result of electrostatic discharge immunity test on voltage monitor was failed. Through the analysis of the test of the unqualified phenomenon such as black screen, and by checking coupling path, some methods of improvement were carried out such as increasing the filtering capacitor, and reducing the coupling area. Finally, the voltage monitor passed electrostatic discharge immunity test.
