This manual is designed to teach students how to select electronic instruments and interpret their readings to get accurate, reliable and cost-effective measurements. It presents the basic theory of the operation of both DC and AC instruments, their capabilities and limitations. This new edition provides updated coverage of topics such as noise, troubleshooting with instruments and DC bridges, including microprocessor bridges, using numerous examples to further explain theory and problems and experiments related to the topics with which they are presented. Included are photographs which show commercially-available service and laboratory tools, with an emphasis on lab quality instruments.

This book offers a complete treatment of both digital and analog instruments; their operation, application, and limitations. Measurement methods and measurement precision are also covered. Commencing with the explanations of units, dimensions, and standards, the text treats measurement errors, then covers electromechanical instruments in one chapter and analog electronics VOMs in another. A single chapter is devoted to the explanation of digital instruments basics and another to digitalvoltmeters and frequency meters. Instrument calibration is also explained, and methods of measuring resistance, inductance, and capacitance are covered in detail. The operation and application of oscilloscopes, both analog and digital, is comprehensively treated, as are a wide variety of laboratory-type electronic instruments.

For courses in Electrical Engineering Laboratory. Designed to be used alone or in conjunction with a laboratory course, this text gives students a practical understanding of electrical laboratory practices and teaches them to become proficient users of electronic measuring instruments. It explains how to select instruments for various measurement applications, how to evaluate their capabilities, how to connect them together, and how operate them properly. to meet the growing demand on students to collect more data and perform sophisticated analysis, this revision omits discussions of outdated analog instruments in favor of the latest digital instruments.

This text on electronic measurement and instrumentation treats the subject in a general way by concentrating on theoretical principles relevant to all measurements, for example electrical, thermal and mechanical. Dr Klaassen follows a system science approach rather than employing the more common method of instrument description. The author deals with all the fundamental aspects of measurement, for example, theory of measurement, systems of units, standards, measurement methods, data acquisition, sampling, multiplexing and aliasing. Also covered are more practical aspects of measurement, including transducers, interference, noise, AD and DA conversion and instrument data buses. This textbook is targeted at engineers and scientists in both industry and academia. It will be of particular interest to those active in the fields of electrical, mechanical and control engineering and will be widely used as a text for undergraduate courses.
