INTRO TO MEASUREMENT AND CALIBRATION DESCRIPTION

Time Requirement
The approximate amount of time needed to complete this course is 6-8 hours.

Contents
An easy to access, menu driven curriculum allows the learner to concentrate on the topics specific to their job requirements. For anyone taking measurements, new hires, students or a refresher for technicians. A logon feature and a printed final test result provides required documentation of training.

Introduction
Definition of metrology; measurements in manufacturing; measurement in the global marketplace; importance of measurement


Development and Concerns of Metrology
Need for better measurements; determine and describe the differences between resolution, accuracy, precision; calibration; Type A Uncertainty, Type B Uncertainty; review questions

Standards and Standardization
Working standards, check standards, international standards, levels of standard
accuracy ís; accuracy ratio between levels of calibration pyramid: requirements of traceability: metrology standardization documents; review questions

Managing the Metrology System
When a metrology system is needed; components of a metrology system; periodic calibration; determining period, fixed time intervals or other means, measurement assurance; record keeping, categories on a good record keeping form, computer record keeping programs, record stickers; documented procedures; components of a procedure, standardization documents, ISO and QS9000, ANSI Z-540, ISO 25, Malcolm Baldrige, training; components of a training program, records, review questions

Making Good Measurements: Elements of a Measurement System
Measuring instrument (calibration); calibration pyramid, relating the instrument to the national standard; unit under test; preparation of the UUT; fixture or jig setup; measuring procedure; operator; analysis of measured data; display of final analyzed result; measurement assurance, isolating errors, capability study, gage R & R; review questions

Units and Measurement Instruments
Length; rulers, height gages, optical comparators, micrometer/calipers, metrology laser, others: roundness, squareness, flatness, surface finish, area, volume, Mass: balances (single-pan, dual pan, electronic) Time: electronic counters, atomic clocks, Temperature; thermometers (liquid-in-glass, metallic stem, thermostats, electrical thermometric, thermistors) flow; flowmeters (rotation, pressure drop, positive displacement) electrical quantities; DC voltages (meters), resistance (multimeters), DC current, AC measures, review questions

Final Test
30 questions, instructor has option of granting Certificate of Completion.
