Digital Alternating Current Parameter Multi-Function Meter 数字式工频交流电参数多用表
The effective value, average value and peak value of alternating large current are measured respectively by means of this meter. The current measured, whose range is from ten to thousands ampere, may be sine wave or non sine wave alternating current. 设计了可分别测出大额交变电流有效值、平均值和峰值的仪表,被测电流可为正弦或非正弦,测量范围为十至一千安培。
