Shelnutt2 said:Lets assume that the oscilloscope is bad. I tried and couldn't seem to get the oscilloscpe to jump up or down at all when I attached a AA battery. What I did was I had a multimeter reading the coltage of the battery then I hooked the oscilloscope probe up to the positive side of the battery. It didn't seem to move the flat line at all.
Wait, an oscilloscope probe has two connectors -- one for the signal, and one for ground. How are you grounding the oscilloscope's probe? You need to connect it to both ends of the battery. And make sure the oscilloscops is on DC coupling.
