Proposal Information (See Instructions)
13. Purpose:
To update the definitions in Appendix D to reflect advances in device calibration technology.
14. Handbook to be Amended:
x NIST Handbook 44 NIST Handbook 130 NIST Handbook 133
Section: Appendix D
Paragraph:Definitions
15. Proposal:
Amend NIST Handbook 44 Appendix D – Definitions as follows:
calibration parameter. – Any adjustable parameter that can affect measurement or performance accuracy and, due to its nature, needs to be updated on an ongoing basis to maintain device accuracy, e.g., span adjustments, linearization factors, and coarse zero adjustments.[2.20, 2.21, 2.24, 3.30, 3.31, 3.32, 3.34, 3.35, 3.37, 5.56(a)]
Multi-point Calibrated Device A device equipped with means toelectronically program linearization factors at multiple measurement points.
16. Justification:
1. Calibration parameter - In 2006, “calibration parameter” was added in sections 3.31, 3.32 3.34, and 3.35; these section now need to be added to the reference string in the definition of “calibration parameter” 2. Multi-point calibrated device - New technology makes it possible to use linearization factors to optimize accuracy at multiple measurement points on devices such as meters, weighing devices, and other devices. This new technology requires a term so that devices capable of being optimized at multiple measurement points can be distinguished from devices with single point calibration.

18. Other Reasons For:
- The term is used in proposals already before the committee, and if those proposals are adopted, the term should be included in the definitions.
19. Other Reasons Against:
20. Evidence:
21. Additional Considerations:
Multi-point calibrated devices are increasingly used as commercial scales and meters. Whether or not the current meter proposals are adopted, the Conference will need to have a term to describe these devices.
