The book provides a clear and systematic understanding of the principles, construction, working, specifications and applications of modern electrical and electronic measuring instruments, which form the backbone of experimental physics and laboratory practice.
The theory portion covers essential topics such as Basics of Measurement and errors, multimeters, electronic voltmeters, AC millivoltmeters, cathode ray oscilloscopes (CRO), signal generators, analysis instruments, digital instruments, and digital multimeters. Each instrument is explained using block diagrams, working principles, specifications and practical applications, enabling students to link theory with real laboratory usage.
The practical section is a strong highlight of the book and includes a wide range of laboratory experiments on basic instrumentation, such as loading effect of meters, limitations of multimeters at high frequencies, measurement of Q-factor, CRO-based measurements of voltage, frequency, phase, rise and fall time, use of frequency counters, distortion measurements and LCR bridge experiments. Viva-voce questions, error analysis, and explanatory notes are included to help students prepare confidently for practical examinations.
Written in a lucid and student-friendly style, the book serves as a reliable companion for classroom learning, laboratory work, university examinations and skill development in experimental physics.
