The Tare function can improve differential pressure measurement uncertainties. Requires the use of an equalizing valve. Use the higher range sensor specifica-
tion when two different ranges are selected.

Accuracy specifications include all effects of linearity, hysteresis, repeatability, temperature, and stability within the specified operating temperature range for
one year.
Note:
Exposure to environmental extremes of temperature, shock, and/or vibration may warrant a more frequent recertification period.
