To calibrate the relative pressure, select the Calibration panel from your IP Module:

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 28.90 inHg.
  3. Reference Figure 35.  Enter the following offset in the Calibration panel for Relative Pressure Offset:

Relative Pressure Offset = 30.12 – 28.90 = 1.22
