This paper presents a method to accurately measure voltage ratios from 1:2 to 1:10 with a calibrated digital voltmeter at voltage ranges of 1V and 10V using a simple resistive voltage divider. The divider can be used as an absolute divider or as a Hamon divider. The achieved accuracy is better than 10-7, comparable to those reported with measurements with Josephson array voltage source.
