About this calibration
Method
Compared with a reference pressure standard at several points across the range, on rising and falling pressure, to show any hysteresis. Your quotation states the test points.
How often
Commonly every 12 months, or sooner for gauges on safety-critical equipment and after overpressure or a knock. Your quality system or inspector sets the interval.
Your certificate
Records the gauge reading against the reference at each point, the error and the measurement uncertainty.
