Currently, the resistive voltage divider (Fluke 752A) has been using as the instrument for extending the voltage range at most of the advanced industrial metrology laboratories. The voltage ratios belonging to this divider can be calibrated by the self-calibration or the external standard. However, the self-calibration is somewhat difficult to need the accomplished technique. Therefore, the calibration of the voltage ratios has planed the method based on a Josephson Junction Array Voltage Standard developed at the NMIJ or a Zener voltage reference (Fluke 732B) as the external standards. A Zener voltage reference used at here is the modified one for obtaining a 1V output. This paper describes how to calibrate the voltage ratios using two external standards and reveals the source of the calibration uncertainty.
