The internal pump requires a separate pressure calibration procedure that replaces the one used in
Section 5.3.1 and 5.3.2.
Note: Ensure that the instrument has been running for at least one hour before any calibration is
performed to ensure sufficient stability.
Note: Ensure units of measure are the same on both the barometer and instrument.
