Analog and Digital Displays
How different readouts support different measurement tasks.
The basics
Analog meters convey trends and changes through pointer movement. Digital displays can make specific numerical values easier to read and can present additional information. Neither style guarantees accuracy by itself.
What to keep in mind
Instrument accuracy depends on the measurement system, not just the presentation. Good interface design supports interpretation without disguising uncertainty or limitations.
