NIST (National Institute of Standards and Technology) Measurement Services: AC-DC Difference Calibrations

摘要

The publication collects and summarizes the specialized information needed to operate the ac-dc difference laboratory and calibration service at the National Institute of Standards and Technology (NIST) in Gaithersburg. It also serves as a convenient reference source for the users of this calibration service and other interested people by documenting the service and its underlying background in considerable detail. It contains the following: an annotated table of contents, a topical index, and a glossary of common ac-dc acronyms; an overview of the service; selected published papers; instructions for the operation of the comparator systems; a schedule for the recalibration and periodic checks of the NIST thermal converters; and a sample report of calibration.
