UI2002C是根据IEC61347-2-3标准新的修订稿的内容，即灯管局部整流效应试验要求而设计的。该仪器模拟当灯管处于局部整流状态时，测试电子镇流器的异常保护功能。该仪器采用不对称脉冲试验方法，3窗口同时显示整流电压、整流电流、整流功率，操作简单，测量高。
UI2002C is designed according to the latest update in IEC 61347-2-3 about thetest requirements for local rectifying effects on tubes. It imitates thecondition when tube is under local rectifying status and tests the abnormalprotection function of ballast by adpoting fluorescent lamp asymmetry pulsetest method with 3 windows for displaying rectified voltage, recitifiedcurrent, and rectified power. It is easy for operation and with high testaccuracy.
