摘　　要：提出以无感电阻为标准器,电流通过电流监测器及无感标准电阻,监测器输出端电压与无感标准电阻两端的电压差由示波器测得,即为电流监测器灵敏度的误差。以型号为2100的电流监测器为例,分别对稳态电流信号和暂态电流信号下监测器的灵敏度误差进行了校准。This paper put forward to use non-inductance resistor as the standard. The current passes through the current monitor and through the standard non-inductance resistor to ground. The voltage drop across the resistor is subtracted from the voltage produced by the current monitor and the difference signal, the error of sensitivity, is observed on an oscilloscope. Take model 2100 as example, current monitor sensitivity error was calibrated under steady state and transient state current signal respectively.
