A New Method of Calibrating Mean Voltmeter
Zhang Yuhai(Department of Basic Science)
A new method of calibrating mean voltmeter is proposed. It is based on the output of direct current that is equal to the mean of inputting alternating current in bridge rectifier circuit of transistor. This method has the chracter of true mean reponse. The accuracy is about± 0.02%. In addition, this method can be used to calibrate distor-hon wave voltage in alternating magnetic measurement.
