TTI's Metrology Concepts is for engineers, managers and technicians who are involved in standards and calibration laboratories and for others who want a clear understanding of the wide range of activities involved in metrology.

This course is applicable to individuals from a wide range of industries such as Defense, Manufacturing, Utilities, Electronics, Automotive, Medical, Telecommunications, Computers, Aerospace and Universities.

Objectives: To provide a basic understanding of the wide range of activities encompassed by personnel working in standards and calibration laboratories. It covers the measurement process, types and correct use of measurement and test equipment, and measurement standards. It provides an opportunity for students to learn about measurement uncertainty and risk analysis. The course includes the procedures necessary to set up and operate a calibration program.

Brief Course Description: Students will receive an in-depth understanding of the most effective methods of establishing and running a first class Standards and Calibration Laboratory. They will also receive an insight into dealing and communicating with industry related organizations such as NIST, ASQC, NCSL etc. and implementing procedures required by ISO 9004, ISO 10012 and ANSI/ASQC/NCSL Z540-1 standards

Students are expected to participate in classroom discussions, to work out classroom examples, to read the text and perform nightly review problems, and to undergo preliminary and final quizzes.
