Course Objectives

QC Training Services’ Introduction to Measurement and Calibration is designed to introduce the metrology and calibration technician and other personnel to the field of metrology. Metrology vocabulary, principles, domains, concepts, and processes are discussed. This first day covers the need for good measurements, principles of metrology, fundamental and derived units, measurement terminology, traceability, dimensional metrology, physical metrology measurements, temperature measuring instruments, and calibration. The second day covers electrical metrology terms, calculations, document standards, calibration systems, and measurement uncertainty.


The introduction reviews standards, principles and devices used in measurement and the specific applications of each. Calibration is a key component of ensuring your measurement system is accurate, and we’ll cover the methods, procedures and environments for an effective calibration system.
