Definitions
- Deadband:
- The maximum hysteresis across all test points: the largest difference between up-scale and down-scale readings at the same set point.
- Hysteresis:
- The difference between the up-scale (increasing) and down-scale (decreasing) reading at a given test point, expressed as a percentage of span.
- Linearity:
- Maximum deviation of the up-scale error curve from a best-fit straight line, expressed as a percentage of span.
