  • How to find solutions for electronic instruments and measurements problems?



By the end of this article, you will have a better understanding of electronic instruments and measurements, and how to use them effectively.


What are electronic instruments and measurements?




Before we dive into the details of the book, let's first define what we mean by electronic instruments and measurements.


Definition and examples of electronic instruments




An electronic instrument is a device that uses electrical signals to measure, display, or control physical quantities. For example, a voltmeter is an electronic instrument that measures voltage, an oscilloscope is an electronic instrument that displays waveforms, and a thermostat is an electronic instrument that controls temperature.


Definition and examples of electronic measurements




An electronic measurement is a process of obtaining numerical values of physical quantities using electronic instruments. For example, measuring the resistance of a resistor using an ohmmeter, measuring the frequency of a signal using a frequency counter, or measuring the power consumption of a circuit using a wattmeter.


Importance and applications of electronic instruments and measurements




Electronic instruments and measurements are important for many reasons. They help us:



  • Understand the behavior and performance of electronic components, circuits, systems, or devices.



  • Verify the design specifications or requirements of electronic systems or devices.



  • Detect faults or errors in electronic systems or devices.



  • Optimize or improve the efficiency or functionality of electronic systems or devices.



  • Ensure the safety or reliability of electronic systems or devices.



Electronic instruments and measurements have many applications in various fields, such as engineering, science, industry, medicine, communication, education, entertainment, and more. For example, electronic instruments and measurements are used to:



  • Design and test electronic circuits or devices, such as microcontrollers, sensors, amplifiers, filters, modulators, etc.



  • Analyze and process signals or data, such as audio, video, images, text, etc.



  • Monitor and control physical processes or systems, such as temperature, pressure, flow, speed, etc.



  • Diagnose and treat medical conditions or diseases, such as electrocardiography, electroencephalography, ultrasound imaging, etc.



  • Transmit and receive information or messages, such as radio, television, telephone, internet, etc.



  • Educate and entertain people, such as games, simulations, experiments, etc.



How to use electronic instruments and measurements?




Now that we know what electronic instruments and measurements are and why they are important, let's see how to use them. In this section, we will discuss the following topics:



  • Functions and characteristics of instruments



  • Electrical units and measurement standards



  • Error in measurement and statistical analysis



  • Selection, care, and use of instruments



Functions and characteristics of instruments




An instrument is a device that performs one or more of the following functions:



  • Sensing: detecting or capturing a physical quantity or phenomenon.



  • Transducing: converting a physical quantity or phenomenon into an electrical signal.



  • Conditioning: modifying or processing an electrical signal to make it suitable for measurement or display.



  • Displaying: presenting an electrical signal or a physical quantity in a readable or understandable form.



  • Recording: storing an electrical signal or a physical quantity for future use or reference.



  • Controlling: regulating or adjusting a physical quantity or phenomenon based on an electrical signal or a desired value.



An instrument has several characteristics that describe its performance or quality. Some of the most common characteristics are:



  • Accuracy: the degree of closeness of the measured value to the true value of the physical quantity.



  • Precision: the degree of repeatability or consistency of the measured value under the same conditions.



  • Resolution: the smallest change in the physical quantity that can be detected by the instrument.



  • Sensitivity: the ratio of the change in the output signal to the change in the input signal of the instrument.



  • Range: the minimum and maximum values of the physical quantity that can be measured by the instrument.



  • Linearity: the degree of proportionality between the output signal and the input signal of the instrument.



Electrical units and measurement standards




To measure a physical quantity using an electronic instrument, we need to express it in terms of electrical units. Electrical units are derived from the seven base units of the International System of Units (SI), which are:



  • Meter (m): unit of length



  • Kilogram (kg): unit of mass



  • Second (s): unit of time



  • Ampere (A): unit of electric current



  • Kelvin (K): unit of thermodynamic temperature



  • Mole (mol): unit of amount of substance



  • Candela (cd): unit of luminous intensity



Some of the most common electrical units are:



  • Volt (V): unit of electric potential difference or electromotive force



  • Ohm (Ω): unit of electric resistance or impedance



  • Coulomb (C): unit of electric charge



  • Farad (F): unit of electric capacitance



  • Hertz (Hz): unit of frequency



  • Watt (W): unit of power



To ensure accuracy and consistency in measurement, we need to compare our instruments with measurement standards. Measurement standards are devices or materials that have known or fixed values of physical quantities. There are three classes of measurement standards:


  • National standards: maintained by national laboratories or organizations that provide reference values for other standards. For example, NIST in USA, NPL in UK, BIPM in France, etc.

  • Laboratory standards: maintained by individual laboratories that calibrate their instruments using national standards. For example, voltmeters, ammeters, ohmmeters, etc.

Working standards: used by technicians or engineers for routine measurements in their work. For example, resistors, capacitors, 71b2f0854b
