he first piece of test equipment that most electronic hobbyists buy is a multimeter. This is probably because it is one of the least expensive items and, also, if you know how to use it properly, one of the most useful.

In this book, different types of multimeters are shown and explained, from the older types of analog moving coil meters like the Simpson 260 to the latest types of multifunction meters like the Fluke 117. Examples have been given and a number of troubleshooting scenarios have been covered from basic voltage measurements with batteries, to more complex troubleshooting problems which require a number of steps. Safety issues have been addressed explaining the different classes of meters and what type of voltages that they are designed to measure and how failure to be constantly vigilant with electricity can result in fatal accidents to persons or irreparable damage to equipment. Explanations are given as to why moving coil meters still have their place (such as in the observation of slowly changing voltages) and as to why every voltage and current measurement affect the circuit being checked.

Radio astronomy is a mystery to the majority of amateur astronomers, yet it is the best subject to turn to when desirous of an expanded knowledge of the sky. This guide intends to instruct complete newcomers to radio astronomy, and provides help for the first steps on the road towards the study of this fascinating subject. In addition to a history of the science behind the pursuit, directions are included for four easy-to-build projects, based around long-term NASA and Stanford Solar Center projects. The first three projects constitute self-contained units available as kits, so there is no need to hunt around for parts. The fourth – more advanced – project encourages readers to do their own research and track down items. Getting Started in Radio Astronomy provides an overall introduction to listening in on the radio spectrum. With details of equipment that really works, a list of suppliers, lists of online help forums, and written by someone who has actually built and operated the tools described, this book contains everything the newcomer to radio astronomy needs to get going.

Do you want to know how to correctly measure and test electronic components or carry out measurements on electrical systems and appliances? Then you can read all about it here in this guide with step by step instructions on how to use a digital multimeter. The DMM is an electronic measuring device for performing electrical measurements. It can be equipped with any number of special functions, but basically voltage (volts), resistance (ohms) and current (amperes) are measured with a DMM. Now that electronic circuits are used almost everywhere, from coffee machines to spacecraft, the demands placed on electrical engineers have increased enormously. Service, repair and installation of complex facilities require diagnostic tools that provide accurate information. Despite that alternative measuring devices are increasing, the digital multimeter still has a large number of users. For many, the digital multimeter has a number of functions such as plugging the probes of the measuring cables into the correct sockets, selecting the measuring range, switching the measuring device on and off and leading the measuring tips to the components to be examined. In addition, you will to measure current and voltage correctly. Although the DMM differ in detail, the basic operating elements are found on all digital multimeters, so that a general operating manual for multimeters is helpful. This guide teaches how to test and measure electrical and electronic components correctly, even if you have no prior experience. You will learn how easy it is to discover faults in home appliances through the use of the multimeter as a measuring device. In this book, you will learn about: How to measure voltage with the multimeter How to measure current with the multimeter How to test battery with the multimeter How to check the mains voltage with the multimeter How to check lambda probe witht the multimeter How to check solar module with multimeter How to measure temperature witht the multimeter How to measure resistance with the multimeter How to use a digital multimeter to check continuity How to measure insulation resistance with the multimeter How to test capacitor with the multimeter And much more........ Measuring and testing electrical components is fun as it helps you troubleshoot and discover faults easily in your electronic home appliances.

Radio and radar astronomy are powerful tools when studying the wonders of the universe, yet they tend to mystify amateur astronomers. This book provides a comprehensive introduction to newcomers, containing everything you need to start observing at radio wavelengths. Written by a mechanical engineer who has actually built and operated the tools described, the book contains a plethora of tested advice and practical resources. This revised edition of the original 2014 book Getting Started in Radio Astronomy provides a complete overview of the latest technology and research, including the newest models and equipment on the market as well as an entirely new section on radio astronomy with software-defined radios (SDRs). Four brand-new beginner projects are included, including bouncing a radar signal off the Moon, detecting the aurora, and tuning into the downlink radio used by astronauts aboard the ISS. Requiring no previous knowledge, no scary mathematics, and no expensive equipment, the book will serve as a fun and digestible reference for any level of astronomers hoping to expand their skills into the radio spectrum.

HOW TO USE A MULTIMETER EFFECIENTLY IN TROUBLESHOOTING AND MEASURING VOLTAGE AND CURRENTwondering how to use a multimeter to carry out various task like troubleshooting circuits and measuring voltage, current and resistance. worry no more because this guide is a good place to start.So... how do I use a multimeter? This guide will show you how to use a digital multimeter (DMM), an indispensable tool that you can use to diagnose circuits, learn about other people's electronic designs, and even test a battery. Hence the 'multi'-'meter' (multiple measurement) name.The most basic things we measure are voltage and current. A multimeter is also great for some basic sanity checks and troubleshooting. Is your circuit not working? Does the switch work? Put a meter on it! The multimeter is your first defense when troubleshooting a system.

This book is about measuring electrical quantities -- voltage, current and resistance -- with meters. By making such measurements, we begin to understand the effects of electricity. Effects which, many times, we can neither see nor feel. Using Your Meter shows you how! It helps you understand how meters work, and how they can be used to make basic electrical measurements in the home, in the workshop, at the office, on the job. It has: easy to follow instructions, clearly illustrated examples, easy to read text, easy to understand applications. The basic concepts of meters, both analog and digital, circuit fundamentals, measurement techniques, and meter measurement examples are presented in six chapters. - Back cover.
