of manual Barometric pressure compensation. We suggest to reset the value according
to the standard barometric pressure table when there is a big change in barometric
pressure to ensure the accuracy of barometric pressure compensation (Please see
Appendix 2 and Appendix 3). For the procedure of Barometric pressure calibration,
refer to 4.9.4.
