Abstract |
We have developed the calibration technique of the VT comparator using nonreactive standard resistors, which evaluates both accuracy and linearity of the VT comparator by comparing experimental values with theoretical values. The correction values of VT comparator obtained by using both our method and wide ratio error VT are consistent within the expanded uncertainty. Furthermore the specification for ratio error of VT comparator have been revaluated. |
