Features: This book is a popular science reader on electrical technology. It categorizes and analyzes electrical instruments commonly used by electricians, explaining their measurement methods and simple maintenance through practical applications. The main content of the book includes the measurement principles of magnetic-dynamic, electromagnetic, and electrodynamic instruments, as well as the working principles and usage methods of multimeters, energy meters, insulation resistance testers, grounding resistance testers, DC bridges, power meters, phase meters, clamp meters, oscilloscopes, signal generators, and electronic counters. The book also provides specific application examples of instruments, tailored to the practical work of low-voltage maintenance electricians, which will help improve their operational skills. Given the widespread use of large-scale integrated circuits in instruments, the variety of digital instruments has also increased. To assist readers in better understanding and utilizing digital instruments, the book introduces not only the working principles of analog instruments but also those of digital instruments with similar functions. This allows readers to compare and learn from each other, enabling them to continuously acquire new scientific knowledge and skills and better serve production practices. This book is primarily aimed at junior and intermediate electrical technology workers in industrial, mining, rural, and enterprise units. It can also serve as supplementary teaching material for training electrical technology workers in enterprises and institutions, as well as a reference for vocational high school students and enthusiasts of electrical technology when learning about electrical engineering knowledge.
