Abstract :
Cryogenic current comparators are widely used for resistance scaling. The high accuracy of these comparators is achieved by flux-sensing using a superconducting quantum interference device (SQUID). At present commonly RF-SQUIDs are used which are no longer commercially available. First experiments for a replacement with DC-SQUIDs are presented
