Waveform analysis clearly explained.
Written for the vehicle technician, 'Automotive Oscilloscopes Waveform Analysis' is the book which answers those questions most technicians yearn for: 'how do I interpret the results of my tests?'. Graham Stokes, the author, has an enviable background: Master Technician, senior automotive manager and specialist diagnostic trainer, with 30 years of industry experience.
This 198-page book, released only April 2017, first briefly reminds us of Electrical Fundamentals and introduces the use of Oscilloscopes. Near 50 pages are devoted to Actuators and a clear analysis - with annotated diagrams - of the waveforms they display. The same for Sensors. These are followed by a chapter on Ignition System Waveform Analysis; another on Network Systems and their analysis. Chapter 7 is devoted to pressure testing using a Pressure Transducer with an oscilloscope.
The Pressure Transducer has become a popular and useful tool to provide a quick and accurate assessment of the condition and operation of internal components of the engine, of transmission systems, of ABS systems, and more. This last chapter has detailed explanations of Intake manifold pressures under different operating conditions; the same for Exhaust pressures; in-cylinder compressions, both cranking and running; crankcase pressure analysis under different conditions; and Fuel pressure testing. A glossary of acronyms is included at the end d of the book.
And the best bit of the book for me: the clear indications of what each waveform means. This also greatly aids understanding how components work, how they communicate, and what can be deduced from the results displayed.
I highly recommend this book as learning aid, as well as a book to be used when performing a test, easily identified by an image of the component.
