text: You can measure DC voltage with an oscilloscope that has a direct-coupled deflection amplifier or terminals for connecting directly to the cathode-ray tube’s deflection plates, but measuring DC voltage using an oscilloscope is only convenient in some situations — e.g., when you’re using the oscilloscope to take other measurements on the same piece of equipment or when you need a high-impedance measuring device and a vacuum tube voltmeter is not available.
