Abstract : The voltage comparator circuit described by Dauphinee and Mooser has been changed so that the forward and reverse resistances of a non-uniform sample can be measured in addition to the average value normally measured. Modifications also allow sample resistances up to 100 megohms to be measured with an error not exceeding 1%, whilst retaining the low resistance sensitivity of better than 0.0001 ohm. (Author)
