Abstract :
A resistance network for verifying the accuracy of resistance measuring instruments up described. The network has been instrument accuracies from 50 Hz to 1 MHz. Relative standard uncertainties of the method range from better than 1/spl times/10/sup -6/ at low frequency to 100/spl times/10/sup -6/ at 1 MHz.
