Any experienced automotive technician will tell you that most diagnosticians develop their skillset over time, they aren't necessarily born with it; I couldn't agree more. My rate of learning and comprehension drastically increased as I began to implement tools used for diagnostics. I'll begin by describing one of the most valuable tools at a diagnostician's disposal, the DSO (Digital Storage Oscilloscope). This tool is highly coveted because it performs all the duties of most DVOMs but also offers a visual representation of what is occurring in the circuit. More importantly, most scopes today support this functionality for multiple channels. It's common to see four channels but some even support eight channels. Seeing multiple circuits operate before your eyes has many benefits. Here are a few of my favorites: 1. History of electrical activity (not just what occurs at a single moment in time) 2. Action/Reaction view (how these multiple signals interact with one another; example: Input vs Output) 3. Information stored in a buffer (no need to babysit the scope, it will capture and save the fault). |
