Abstract

We report the preliminary results of a project to improve the NIST calibration service for low-voltage thermal transfer standards. Central to this project is the direct comparison of the low-voltage ranges of a thermal transfer standard to an intrinsic ac standard. The combination of a new intrinsic standard for ac waveforms, a scaling procedure using multijunction thermal converters (MJTCs), and the relocation of the calibration service to the Fundamental Electrical Measurements Group will result in a significant improvement in both the uncertainties and turnaround times for thermal transfer standard calibrations at low voltages.
