Research of the Internal Resistance of the Active Network Measuring Meter

The paper rintroduced a new method of measuring internal resistance of the active network . A new kind of measuring in-strument based on the method was developed .Hardwares of the instrument were listed , its working principle was described in de-tail , its circuit diagram and procedure flow chart were given , too . Measuring tests showed that the instrument had a good stability , high degree of measurment accuracy . In addition , it was convenient to use and cheap with its simple structure . Therefore , it is a perfect instrument of measuring internal resistance of the active network.
