Topic: Pressure Uncertainty Budgets when using a Modular Pressure Controller
Speaker: Tim Francis, Fluke Calibration
Modular Pressure Controllers are a common and useful tool for performing pressure calibrations. The modular design splits the different tasks that the controller/calibrator performs into separate modules, providing more flexibility, expandability, and simplifies support. In splitting the tasks into multiple modules, it also splits the different sources of uncertainty. This presentation examines the different sources of uncertainty when using pressure controllers, how those sources are impacted by a modular design, and any special considerations when using modular pressure controllers.
Topic: Commercial Solution for Wattmeter Calibration
Speaker: Kevin Kaufman, Tegam
TEGAM completed a contract to repair and modernize an aging wattmeter calibrator for the U.S. Air Force Primary Standards Laboratory in Heath, OH. Knowledge gained about the application, market and solution led to the development of a commercial solution. This presentation discusses the history of the Air Force project and the solution that is now available on the market.

Topic: New Developments in the Quantum Hall Resistance Standard (An Intrinsic Standard for the Ohm)
Speaker: Mike Frisz, Measurements International
This presentation discusses the improvements in the Quantum Hall Resistance System. The QHR system consisted of three main parts: cryogenics, QHR sample and the measurement bridge. First developed in late 1990s improvements were made to all areas including the sample, the technique for changing the samples, automation, power line protection and the measurement bridge technology. The latest technology combines the improvements with the capability for the system to collect and re-liquefy the helium gas that boils off for a very minimal loss of helium. Improvements to the measurement technology were required for measuring Vxy on contacts 1 & 2 and 3 & 4 on the 1 = 2 plateau using a new room temperature direct current comparator ratio measurement bridge known as the Accubridge® 6020Q to lower the measurement uncertainty in the range of 0.005 ppm or less. The QHR System verification is referenced to the Institute for National Measurement Standards (INMS) at the National Research Council (NRC), Canada and METAS in Switzerland.
