Title: Analysis of measurement uncertainty for DC low voltage calibration
Abstract: Based on the low EMF divider and temperature-controlled box and other standard instrument,the low DC voltage calibration system is built.The measurement uncertainty sources are analyzed,and the typical value is given.The results show that the measurement uncertainty at 1μV is 2.2%,so that it is satisfied for calibration for DC digital nanovoltmeter.
