A Dual-Balance High-Resistance Bridge in the Range of 1 T{O} to 100 T{O}

May 1, 2000
Author(s)
Dean G. Jarrett
The NIST dual-balance guarded active-arm bridge, using a third dc source and a second detector to balance the guard network, is described. Improvements to the NIST guarded active-arm bridge and the design and construction of improved high resistance

A Comparison of 1 T O} and 10 T O} High-Resistance Standards Between NIST and Sandia

August 1, 1999
Author(s)
Dean G. Jarrett, Ronald F. Dziuba, Marlin E. Kraft
NIST-built 10 T ω and commercial 1 T ω standard resistors were hand carried between NIST and Sandia for a high resistance comparison. The comparison tested the ruggedness of the new NIST-built standard resistors, provided a check of the scaling between the

Evaluation of Guarded High-Resistance Hamon Transfer Standards

April 1, 1999
Author(s)
Dean G. Jarrett
An improved design for a guarded transfer standard in the resistance range 1 M ω to 100 G ω is described. Existing transfer standards and their limitations are reviewed along with a description of guard circuit theory. Measurements made to evaluate the

Fabrication of High-Value Standard Resistors

April 1, 1999
Author(s)
Ronald F. Dziuba, Dean G. Jarrett, L. L. Scott, Andrew J. Secula
The National Institute of Standards and Technology (NIST) has fabricated stable, transportable 10 MΩ} and 1 GΩ} standard resistors for use in an international comparison of high resistances. This fabrication process is being applied to the construction of

A Guarded Transfer Standard for High Resistance Measurements

July 1, 1998
Author(s)
Dean G. Jarrett
An improved design for a guarded transfer standard in the resistance range 1 M[Ω] to 100 G[Ω] is described. Existing transfer standards and limitations are reviewed. Interchangeable guard networks are used in the improved transfer standards to ensure
