A.K. Sawhney's Comprehensive Guide to Electrical and Electronic Measurements and Instrumentation: PDF Free Download
Instrumentation and measurement are two essential aspects of electrical and electronic engineering. Instrumentation refers to the devices and systems that are used to measure, monitor, control, and record physical quantities such as voltage, current, resistance, power, energy, frequency, phase, temperature, pressure, flow, etc. Measurement refers to the process of obtaining accurate and reliable data about these quantities using appropriate instruments and methods.
