The authors describe a DC network based on the Warshawsky generalisation of a Wheatstone bridge to four-terminal resistance measurement which can automatically compare the values of a number of four-terminal resistors of the same nominal value between 1 Omega and 10<sup>4</sup> Omega with an accuracy of better than 1 in 10<sup>8</sup> when 1 mW is dissipated in them.
