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. This guide is primarily aimed at beginners and those of limited experience of electronics. Chapter one covers the basics of analogue and digital multimeters, discussing the relative merits and the limitations of two types. In chapter two various methods of components checking are described, including tests for transistors, thyristors, resistors, capacitors and diodes. Circuit testing is covered in chapter three, with subjects such as voltage, current and continuity checks being discussed. In the main little or no previous knowledge of experience is assumed. Using there simple components and circuit testing techniques the reader should be able to confidently tackle servicing of most electronic projects.
