Abstract
This paper describes realization of the ultrahigh-omic resistance scale in the range from 10 GΩ up to 100 TΩ at CMI. The scale realization is based on measurement of standards with different nominal values at various voltage levels, selected in such a way, that same nominal current is preserved during measurement of different standards. Measurement circuit consists of the measured standard, an electrometer and is energized from a voltage calibrator. The described method was used during Supplementary Comparison EURAMET.EM-S32.
