- 据此实现的DVF-1型智能数字电压频率测量仪的VFC系统,满度非线性误差达到了3×10~(-6),远优于NSC公司相同原理精密器件LM331的1×10~(-4)非线性水平。 Based on this, the design procedure for the low nonlinearity V/F converter is developed and a simple compensating method is given, which is proved to be successful on the DVM of Model DVF-1. The V/F converter used in the DVF-1 provides a nonlinearity within 3ppm, which is much better than that of LM 331 developed by NSC Company.
