As we've covered the waveform database before, now we'll explain how to use it, or any signal waveform database, for that matter.
The idea, is to have some baseline signal to compare to. Most auto repair diagnostic is about relationships. Here's how to do it.
The engine has a pesky misfire. Ignition waveforms are easy to read, if you know how. So, after connecting the ignition scope, and taking a snapshot, we come up with our vehicle waveform. Now, all ignition waveforms, are read in the same manner. Why? Because an ignition signal of a failing cylinder, is the same, regardless. What you are probably going to separate, is the engine depending on the cylinders, for easy of use.
