We present the latest improvements in the traceable measurement and generation of small electric currents. A central tool in our traceability chain for small direct currents is a new binary cryogenic current comparator (CCC) with a total of 18276 turns. This 14-bit CCC is well suited for the calibration of highvalue resistors and current amplifiers, but… CONTINUE READING
