They extend high accuracy measurements beyond the avail- able limits of self-contained dc ammeters and the DCCS Current Shunts can be used as standard reference resistors. The DCCS Current Shunts are low cost 4-terminal calibraƟ on resistors that com- bine high accuracy , class 0.02, long term stability and permanence of calibraƟ on in a compact unit. Constructed using carefully selected low temperature coeffi cient Man- ganin® or Zeranin® wire, depending on the value, and mounted to ensure mechanical stability, these current shunts will provide a cost-eff ecƟ ve addiƟ on to any laboratory or workshop.
