[IEEE 2018 Conference on Precision Electromagnetic Measurements (CPEM 2018) - Paris, France (2018.7.8-2018.7.13)] 2018 Conference on Precision Electromagnetic Measurements (CPEM 2018) - Experiments to Extend the Retrace Specification of Fluke Zener Reference Standards

摘要： Fluke zener reference standards were designed to operate under constant power, whether it is from line power or from the batteries. Fluke has a published specification associated with the loss of power to the device under laboratory conditions for up to 24 hours (Retrace). Fluke has performed research and development on a new generation of Zener Reference standards, and as part of the research, experiments were conducted to quantify the uncertainty associated with removing power to the units for extended periods of time. The results of the experiment are presented, with interpretation of the data.
