此方法就是用一台经过中国计量科学研究院电学处检定过的性能比较稳定的YY10型作转换标准。并且,采用热偶电动势差值法,以消除交、直流电压源及电流源不稳定而带来的影响。因而就可以利用与XF1b配套的交直流电压源及电流源,从而能够比较容易地实现YY10的电压及电流交、直流转换误差的检定。当在XF1b校验台上进行电压的交直流转换误差检定时,将被检的YY10的电压输入 This method is to use a Chinese Institute of Metrology Institute of Electrical verified the performance of more stable YY10 type for conversion criteria. And, the use of thermocouple difference method to eliminate AC, DC voltage source and the current source of instability and the impact. Therefore, we can use XF1b supporting AC and DC voltage source and current source, which can be relatively easy to achieve YY10 AC and DC, DC conversion error of the test. When the XF1b calibration station for voltage AC-DC conversion error test, will be seized YY10 voltage input
