 You know a fluke something to that level that's going to respond so fast and keep in mind I've actually seen this I can prove this in a class where a voltmeter will actually lie to you if it's not if we're testing something that requires too fast of a signal change and It'll prove where you actually need a lab scope. I don't think you need a lab scope for what you're doing here It would be nice, but your eye will also trick you and lie to you as well so I think you want to test this using a meter and
