EEVblog #584 - What Effect Does Your Multimeter Input Impedance Have?

What effect does your multimeter input impedance have on the circuit you are measuring? Dave shows a practical example of how it can really screw things up if you aren't watching out for it. NOTE: For those who want to comment on the fact that there are other ways to measure this in my specific circumstance, yes, there are several, but the point of the video is to show what happens when you measure a circuit node of even moderate resistance.
