Key Takeaways: Resolution Uncertainty Definition: The smallest change in a quantity being measured that causes a perceptible change in the indication of the display. Digital Displays: Uncertainty is calculated as Resolution / (2√(3)). Analog Displays: Typically evaluated as Resolution / √(3) or Resolution / (2√(3)) (if using half-scale readability) depending on the lab’s policy. Distribution: […]
Quantifying UUT resolution uncertainty can vary significantly depending upon a device’s design, functionality, and operation. The resolution of a digital device may not be evaluated in the same manner as an analog device or artifact. Additionally, the resolution of similar devices may vary depending on how it is used. This makes the evaluation of resolution uncertainty […]
