Gauge Pressure Accuracy (P1, P2, and APMi)
Includes all effects of linearity, hysteresis, repeatability, temperature, and stability with the operating temperature range for one year.
Note: Exposure to environmental extremes of temperature, shock, or vibration may warrant a more frequent calibration period.
The HPC50 Series must be exercised and re-zeroed whenever exposed to significant changes in environmental conditions to achieve these specifications. 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 zero
reading (or return to the same ambient barometric reading).
