Calibration of most parameters is not required, with the exception of Relative Pressure,
which must be calibrated to sea-level to account for altitude effects. For more information on
sea-level pressure calibration, please reference note (3) below.
4.6.9.1 Relative Barometric Pressure Calibration Example
The following is an example of calibrating the relative pressure. Your results will vary.
1. The local relative pressure from TV, the newspaper or the internet for the official
station in your area is 30.12 inHg.
2. From the Live Data panel, your absolute pressure (measured, and not corrected to
sea-level) reads 30.47 inHg.
