- Abstract:
- Irreversible resistance changes of Thomas type 1 ohm resistors according to temporary temperature change is about 0.03 ppm/y in average by reported results of PTB, IEN and NIST, but the behavior did not occur in NML 1 ohm resistors under the same condition. By qualitative analysis based on thermal stress and strain, it is considered that a major element of the behavior is thermal stress by different thermal expansions of coils and mandrels.
