A precision set-up and method for calibrating a DC voltage divider's ratios from 10 V to 1000 V

A precision set-up and method for calibrating the division ratios of a resistive divider for DC-voltage in the range 10 V to 1000 V is described. The method requires equipment commonly available in most standard laboratories. Uncertainties better than 3/spl times/10/sup -7/ (k = 2) in the ratio is achieved.
