(四)、输出纹波电压及噪音测试 1、测试条件：交流输入电压 220V，输出满载(对于多路输出，各路均满载) (可根据需要设定交流输入电压 90V，220V，265V，满载输出条件下测试)。 2、测试方法：测试时，示波器 TIME/DIV 档置 10uS/div，带宽置 20MHz，读取示波器显示的输出电压峰 -峰值即为输出纹波电压(包含毛刺在内的峰-峰值为纹波+噪音)。 3、输出杂音测试(选测内容，分为峰-峰值杂音，电话衡重杂音，宽频杂音，离散杂音)。 (五)、输出过压保护功能测试 1、测试条件：交流输入电压 220V，输出满载条件下测试。 (可根据需要加测交流输入电压 90V-100V，满载输出条件下过压保护功能)。 2、测试判定方法： (1)调整输出电位器使输出电压缓慢升高，直到电源输出突然关断(输出电压突变为零，电源处于保护状态)， 此时输出电压值即为输出过压保护点。 (2)若无输出调整电位器，可在电源满载工作时，于输出端外加直流电压并慢慢调高，直到电源保护无输出。
