EVT F4 Electrical Systems and Components Practice Test

Digital meters read measurements as numeric values shown on a display, because they use an analog-to-digital converter and digital processing. That digital path provides a defined, stable reference and high resolution, so the readout is precise and less prone to human reading errors. The result is better DC accuracy overall.

Analog meters, by contrast, rely on a physical pointer moving over a scale. The reading is affected by mechanical factors—tolerances in the coil or magnet, scale nonlinearity, pointer alignment, damping, and parallax—which limit accuracy and make reading less consistent, especially for DC signals. Capacitance meters are a different instrument type used for measuring capacitance, not primary DC voltage or current accuracy, so they don’t fit the stated criteria.

So the device with a digital display and generally higher DC accuracy is the digital meter.
