COMMON ERROR SOURCES IN USING A SERIES-RESISTORS-TYPE VOLTAGE DIVIDERBELOW THE LEVEL OF 0.01 PPM

A series-resistors-type voltage divider is one of the most commonly us ed dividers, We have carefully analyzed various error sources such as leakage current, normal mode rejection ratio of the voltmeter, tempera ture coefficient, and others, The KRISS' 10:1 divider which was used f or 10-V calibration was chosen for this study, Here, we would like to describe some common error sources and their effects which should be t aken into account in the level of 10(-8) or below for the series-resis tors type voltage dividers.
