Oh, they may not show it, but deep down inside, they get nervous. How do they work, how do you get the pattern on the screen, and what does the pattern mean? How do you know if the signal is good or bad? That's what this book is about.\u003c\/p\u003e\n\u003cp\u003eThe purpose of this book is to make it simple. You'll learn what you need to know to start successfully using a lab scope including:\u003c\/p\u003e\n\u003cp\u003e- How does a lab scope work? (in very simple terms)\u003cbr\u003e- When you look at a pattern on the scope, what are you seeing, and how do you know if it is bad?\u003cbr\u003e- How do you get a pattern on the scope, how do you do the adjustments to make the pattern look right?\u003cbr\u003e- What do you do when you can't get a pattern on the screen at all* (A lot of guys have this problem, but don't admit it to their friends?)\u003cbr\u003e- What are some of the different things you can do and see with the lab scope* (Most technicians don't know how much diagnosis you can do with an inexpensive scope, and a few attachments.)\u003cbr\u003e- What are the different types of scopes? And what are they good for? Do you have to spend a lot of money for a really expensive one? And where would you get one?\u003cbr\u003e- Where and how do you hook up the scope to the circuit? Does it make much difference?\u003c\/p\u003e\n\u003cp\u003eThis book consists of 62-pages and is written in a down-to-earth manner so you can quickly learn what you need to know.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAbout the author:\u003c\/b\u003e\u003cbr\u003eSteve McAfee is a respected automotive instructor at Skyline College in San Bruno California.
