This paper presents a method to accurately measure voltage ratios from 1:2 to 1:10 with a calibrated digital voltmeter (DVM) at voltage ranges of 1-10 V 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 (JAVS).
