Main research staff Gu Tianxiang Yang Guoqiang Yang Hongmo Yin Hong Yang Steel The results of the dual CPU technology, respectively, control CRT display and machine measurement, control and calculation. And under the control of the single-chip 8031, the use of vector voltage and current methods and free-axis measurement principle and the use of sinusoidal signal digital synthesis, digital phase shift, D / A converter digital phase-sensitive detection and charge balance multi-oblique A / D conversion technology, coupled with the design of a full set of software to achieve automatic zero, self-calibration and self-test function, so that the instrument has high accuracy and rich features. The instrument is mainly used for measuring departments at all levels of the AC measuring instruments and comparison, but also can be used for the production site and laboratory
