The guide provides an introduction to measurement, discussing the significance of good measurement and its relevance to electronic and electrical engineering.
NPL is responsible for maintaining the national standards and making them available to industry throughout the country. Life in the 21st century relies heavily on precision measurement. As Barry Brooks, President of the IET, states in his foreword:
"Satnav systems are dependent on ultra-stable clocks; different electrical components work together in personal electronic goods; and food producers use the optimal temperature necessary for perfection to prevent energy wastage. Precision measurement is at the heart of each of these products and services."
This guide provides sufficient information to enable an electronic or electrical engineer to carry out good measurement practice, learn about the International System of Units (SI) and understand how their measurements relate to national standards. Through the practical application of theory, it demonstrates how to read instrument specifications, introduce a defined measurement procedure and carry out uncertainty analysis.
Good measurement is crucial for a successful career in electronic or electrical engineering and this guide will help engineers improve their measurement capabilities.
