10 T? and 100 T? Resistance Comparison between NIST and AIST



Dean G. Jarrett, Takehiko Oe, Nobu Kaneko, Shamith U. Payagala


We report the results of a comparison of 10 TΩ and 100 TΩ high resistance standards between the National Institute of Standards and Technology (NIST) and the National Institute for Advanced Industrial Science and Technology (AIST). Three standard resistors were hand carried between both laboratories, a 100 TΩ from NIST and a 10 TΩ and 100 TΩ from AIST. The two laboratories agreed to within 80 x 10-6 at 10 TΩ and 500 x 10-6 at 100 TΩ. The comparison results have given both laboratories an external check of their measurement systems and scaling processes to 100 TΩ.
