Calibrate Relative Pressure, Observer Series.

Select the Calibration tab to view your calibration data from the weather station.

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 the above below.  Enter the following offset in the Calibration panel for Relative Pressure Offset:

Relative Pressure Offset = 30.12 – 28.90 = 1.22
