Thanks to Eevblog I've gotten a lot of valuable information from using my basic scope. I keep finding new features, but there's one feature/issue I cannot seem to resolve.
Let's say I have a measuring point where I want to see changes in the millivolts in the 24v range. Meaning, the signal averages 24v but there's fluctuations and I want to "zoom in" on those. I can set the Y scale to let's say 5v but that doesn't really allow me the granularity and I'll see mainly a straight line. If I set the Y axis to .5V - the line goes WAY off and finding it may or may not be possible with the "adjust zero" option on the Y axis. How do you get the granularity of changes if it's not close to the 0v line? Is there a trick here, or do you just turn the know 100 times until you get there?
If it's relevant, my scope is a Rigol DS1054Z.
