Accuracy (Reference – Includes
combined effects of linearity,
hysteresis, and repeatability)
•
Accuracy includes residual error
after averaging successive
readings.
• For FOUNDATION Fieldbus use
Digital Mode specifications. For
HART use Analog Mode
specifications.
In Analog Mode:
±0.1% of calibrated span or upper range value (URV), whichever is
greater.
For URV below reference point (20 psi), accuracy equals:
±0.05 + 0.05
