Easy-to-understand measurement practices
 |
Description
Book Introduction
Electrical engineers who maintain and manage electrical equipment must always be aware of the condition of the electrical equipment, and if any defects, abnormalities, or signs of failure are discovered, they must respond appropriately to ensure electrical security.
If you fully understand the operating principles and characteristics of measuring instruments, you can avoid major mistakes and respond to changes in measurement conditions. In "Easy-to-Understand Measurement Practice," basic and convenient measuring instruments used in the maintenance and management of personal electrical equipment are provided as examples, and their measurement principles, handling methods, and precautions during measurement are explained in detail.
In addition, various photos and diagrams are included to make it easy to understand measurement points and precautions, and basic matters related to measurement, such as handling methods of measured values, precision, and methods for judging errors, as well as matters related to quality control, such as instrument calibration and traceability, are explained in detail.
