How do I Calibrate Barometer (Relative Pressure), ObserverIP Series?
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.
- The local relative pressure from TV, the newspaper or the internet for the official station in your area is 30.12 inHg.
- From the Live Data panel, your absolute pressure (measured, and not corrected to sea-level) reads 28.90 inHg.
- Reference Figure 35. Enter the following offset in the Calibration panel for Relative Pressure Offset:
Relative Pressure Offset = 30.12 – 28.90 = 1.22
