 see figure 2 , it can be seen from the working principle diagram that the measuring device is used to detect the leakage current of the device under test 1 in the working state. The leakage current produces a voltage drop on the 1k-Ω resistor in the measuring device. LED display after true RMS conversion, linear adjustment, and AD conversion. Due to the large measurement range of 0.1μA-10mA, it is displayed in segments, and it is equipped with an out-of-tolerance alarm function, which is convenient for users to use.
 According to the different frequency characteristics of the measured object, the measuring device can make reasonable attenuation in the measurement network by setting various parameters, so that it conforms to the standard frequency characteristic curve.
 The LED display device for displaying the measured value must accurately display the DC signal and the high-frequency true RMS signal generated in the measurement network, and must confo...
