PREFACE
Many technicians (and engineers too!) who work exclusively with receiver circuitry or with specialized electronic devices, tend to throw up their hands when confronted by an oscilloscope, generator, or complex test-equipment problem. This attitude is unjustified. The electronic circuitry in test equipment is no more complicated than the circuits of television and radio receivers that are being serviced every day.
This manual of test-equipment circuits and specifications is published for technicians, design engineers, and students. The content has been planned to assist technicians in maintenance of their instruments, acquaint design engineers with standard practices, and enlighten students concerning "what goes on inside test equipment."
Test Equipment Circuit Manual contains specifications and schematic diagrams representative of most service-type instruments in current use. It would be impossible to include all test-equipment circuits; however, it is hoped that this manual will help you to understand not only the circuits presented, but test-equipment circuitry in general.

ELECTRONIC TEST INSTRUMENT HANDBOOK
BY JOSEPH A. RISSE
About the Author
Few people are better qualified to author this text than Joe Risse. Currently Director of the School of Electronics, International Correspondence Schools, Mr. Risse has had a long career in teaching electronics as well as in developing training programs. With this background, he is not only an expert, but also highly talented in passing along his knowledge for the benefit of others.
A complete reference handbook, containing all you need to know about every basic piece of test equipment used in making all types of electronic tests and measurements. This volume thoroughly explains operating principles, functions, and applications for various meters, generators, testers, oscilloscopes, etc. Included are instruments used in testing and maintaining home-entertainment devices, communications equipment, and industrial and commercial systems. Schematics and drawings, with easy-to-follow hints on circuit repair and general equipment maintenance, are also included. The book further provides complete information on how, when, and where each instrument should be used, as well as how to achieve maximum accuracy and efficiency-practical knowledge which will help anyone who works with test equipment to make the most effective use of various testing and measuring devices.
-----
PREFACE
Many testing, measuring, and indicating devices have been developed for the rapidly-growing field of electronics. In addition to the wide variety of test instruments found in electronics service shops, there are hundreds of precision laboratory and scientific testing and measuring instruments. The broad categories include ammeters, ohmmeters, voltmeters, wattmeters, oscilloscopes, various types of signal generators, and numerous component testers--each designed to meet the various demands of the electronics industry.
This book is devoted to a practical analysis of all these instruments, including their operating principles, functions, and applications. The content is detailed, providing an in-depth treatment of "what makes the instruments tick," so that you can better understand, use, and even calibrate and repair test equipment. Typical versions of each type of instrument are discussed so that each category is well represented. Where appropriate, instruments that deviate from the norm are analyzed and discussed.
The instruments described in this book range from basic types to those used in specialized fields. Therefore, whether you are a student of electronics; a technician in radio-TV, communications, sound and audio, or industrial fields; or a technician or engineer engaged in precision laboratory work, the vast information in this book will be invaluable to you.

Gasoline Fuel-Injection System K-Jetronic: Technical Instruction 96/97 Review

This is a 37 page manual showing details of the Bosch K-Jetronic Gasoline FI system. It includes operation, components, and wiring diagrams and photos. It is specific to the title system, but this is the most widely used gasoline FI system in the world. A little pricey at $11.95 US, which is 80 of my dollars.

(More customer reviews)
This software is very user friendly, and has nice graphics, a real estate term glossary, calculator, and various test taking options. You can choose to design your own exam, by topic and also by the number of questions in each subject. You may scramble the question order (shuffle), choose to have sound when a question is missed, or set a reminder alarm clock, etc. There are 11 practice tests that are designed to be taken in a specific exam order for optimum learning efficiency. This software will keep track of when you took an exam and how high that you scored on any exam. A maximum of up to four answer attempts may be made on any question during an exam. After you complete the exam you may choose to: (1) retake the entire exam again, or (2) just retake the questions that you missed, or (3) retake the "wild guesses." These are the questions that you need to study the most for the state sale's exam (any question that you missed three times in a row). You may quit the test at any time and continue the exam at a later date right where you had stopped. The exam clock works like a stop watch, and it will run from the moment the user clicks "next question" until the correct answer is finally chosen for a question, then an answer explanation will appear.
