- The barometer measures the air pressures and displays tendencies in the weather.
- As a general rule, the higher a person goes (ascent/terrain), the lower the barometric pressure will be.
- An increase in air pressure usually signifies an improvement in the weather.
- A decrease in air pressure usually means that bad weather is on its way.
- The air pressure is displayed with an accuracy of 1 hPa (hectopascals).
- The barometer can measure and display a range from 260 hPa to 1000 hPa.
