Title: Dynamic Calibration for Instruments
Author(s): Charles Hagwood*+
Companies: National Institute of Standards and Technology
Address: 100 Bureau Drive, Gaithersburg, MD, 20899-8980,
Keywords: calibration ; dynamic linear model ; pressure instruments
Abstract:

Often during their usable lifetime instruments are calibrated and recalibrated several times. The goal is to take advantage of these sequentially collected calibration data sets. Instruments drift between calibrations and adapting the dynamic linear model to this calibration problem allows one to incorporate instrument drift into the calibration equation. It is shown that dynamic calibrators perform better than static calibrators.
