Specifications
accuracy
Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.
Gauges must be exercised whenever exposed to significant changes in environmental conditions to achieve these specifications, and (if not an absolute
model), rezeroed. To exercise a gauge, cycle the gauge between zero (ambient barometric pressure) and the pressure of interest. A properly exercised gauge
will return to a perfect zero reading (or return to the same ambient barometric reading). Absolute versions of
XP2is have a “B” in front of “XP2I” in the part
number.
Exposure to environmental extremes of temperature, shock and/or vibration may warrant a more frequent recertification period.
