เนื้อหาย่อ : Preface ok is intended as a reference that new or experienced technicians valuable in the classroom and on the job. The material in this text vered with acceptable depth in as little as 8 weeks with advanced yet also serves well as a basic text for those just beginning a electronics repair. Together with suitable texts on basic theory, me is particularly valuable during the hands-on repair of actual sic difference in using this text as a supplement with either an a full 2-year electronics program will be determined by the depth the students will be taken into real-world troubleshooting situa- is strongly suggested that students be given the opportunity to ry the methods presented herein, and that hands-on experience be sed with lectures covering the material in detail. most texts, the instructor can choose to begin at the front, middle, without necessarily having to build on previous information to ther subjects besides troubleshooting that may be taught concur- e order of topics in this book begins with system troubleshooting resses to component removal and replacement. Each topic is cov- he point where it is most appropriate. The use of a bench power r instance, is covered when it is most timely, after the equipment and before the technician begins to troubleshoot with a voltmeter. flow of the book may appear to be somewhat scattered to those ed to topics being covered in a less chronological, modular form. the topics are ranged, as closely as possible, in a logical, con- der. rred text identifies basic concepts and material pertinent to the ooting topic of the moment, information that will prove beneficial try-level technician. More advanced students may chose to review, kip these subjects entirely. isites for the use of this book are training in basic electronics, bipolar transistors, and in digital circuits. Other subjects and mponents are explained in this text as they directly apply to troubleshooting. re three general types of jobs involving electronic problem detec- repair. The first is the one that most commonly comes to mind describes an electronic technician, that of returning "veteran" t to service. "Veteran" equipment has worked at one time, but f a normal failure or abuse, it no longer functions properly or has gether. The majority of electronic technicians find employment in of job. There are two subdivisions of this kind of work: that of the nician who goes to the customer's site to repair equipment and the hnician who repairs incoming equipment at a fixed location. Some ire both field and bench work.
