Digital Accuracy*
0.2 hPa (25°C)
0.3 hPa (-40°C to +60°C)
Analog Accuracy** 0.05% of analog pressure range
Analog Temperature
Dependence**
0.0017% of analog pressure
range per °C (25°C reference)

*
Defined as ±1 standard deviation from NIST-traceable
pressure reference in clean, dry air. Includes non-
linearity, hysteresis, repeatability, and calibration
uncertainty.
** Defined as ±1 standard deviation from ideal analog
output. Total analog output accuracy is the root sum
square of digital accuracy, analog accuracy, and analog
temperature dependence.
