Scope

This verification system table is applicable to the verification procedures of DC resistance measuring instruments with a nominal resistance value of 10-4 Ω to 108 Ω.
This verification system table specifies the use of the national reference for the DC resistance unit (ohm) in this range, including a complete set of basic metrological parameters for reference instruments, as well as the transfer procedure for transferring resistance values from the national reference through metrological standard instruments to working metrological instruments, and specifies their uncertainties and basic verification methods.
