Barometric Pressure Differential Pointer
This pointer indicates the relative difference between the most recent barometric pressure reading indicated on the barometric pressure graph (page E-62), and the current barometric pressure value displayed in the Barometer/Thermometer Mode (page E-61).
Reading Barometric Pressure Differential Pointer
Pressure differential is indicated in the range of ±10 hPa, in 1-hPa units.
- The nearby illustration, for example, shows what the pointer would indicate when the calculated pressure differential is approximately – 5 hPa (approximately – 0.15 inHg).
- Barometric pressure is calculated and displayed using hPa as the standard. The barometric pressure differential also can be read in inHg units as shown in the illustration (1 hPa = 0.03 inHg).
