Features: This book takes practicality as its starting point, using relatively easy-to-understand language to explain the structure and principles of pointers, digital multimeters, their usage methods, and practical testing techniques. It introduces methods for testing electronic components such as resistors, capacitors, diodes, transistors, field-effect transistors, and triacs with multimeters. It also covers testing optoelectronic devices like photodiodes, phototransistors, optocouplers, laser diodes, LED digital displays, and LCDs, as well as methods and techniques for testing basic electrical control circuits and motors. The book includes the structure, principles, and maintenance techniques of some household appliances, such as electric irons, electric blankets, electric water heaters, water dispensers, electric shower heaters, energy-saving lights, dimmable lights, rice cookers, electronic pulse igniters, microwave ovens,, food processors, vacuum cleaners, and washing machines. In terms of household appliance maintenance, the book provides detailed explanations of fault cases, including their symptoms and troubleshooting processes, making it highly targeted and practical. The book is richly illustrated and easy to understand, making it suitable for beginners and intermediate-level household appliance repair personnel, radio enthusiasts, and also serves as supplementary teaching material for vocational colleges, secondary schools, technical schools, and short-term training courses. The book explains the structure and principles of pointers and digital multimeters, their usage methods, and practical testing techniques. It introduces methods for testing resistors, capacitors, transistors, field-effect transistors, and other optoelectronic devices, as well as techniques for testing basic electrical control circuits and motors.
