As lab scope users get comfortable using their scopes and understanding voltage waveforms, they will eventually want to learn to use them in new and different ways. Of course on of the things that makes a lab scope so powerful is that you can connect it to many different transducers, including many devices that were initially meant for use with DMMs. This would include probes to measure temperature, pressure, vacuum, knock and noise sensors, and position and speed sensors. In fact, many surplus sensors removed from the systems you are already working on can be adapted to serve as input devices for your scope. If you are ready to start experimenting beyond conventional time/voltage waveforms on your scope, a good place to start is with current waveforms. After that, you may want to look at vacuum waveforms.
