Notes to hPa sensitivity setting for weather forecasting:
The hPa (Hekto-Pascal) pressure sensitivity can be set to suit the user's
requirement for weather forecasting from 2 hPa to 4 hPa (see Basic
Programming below). For areas that experience frequent changes in
air pressure (which does not necessarily reflect a change in the
weather) requires a higher hPa setting compared to an area where the
air pressure is stagnant. For example if 3 hPa is selected, then there
must be a fall or rise in air pressure of at least 3 hPa before the weather
station will register this as a change in weather.
Air Pressure (LCD Section 2)
The air pressure reading is displayed here. Press the PRESSURE key
to toggle between relative and absolute air pressure displays.
Notes to Absolute and Relative Air Pressure:
Absolute air pressure provides the display of the true measured air
pressure of the current time and location. This is not programmable and
the absolute air pressure range of the weather station is from 300 hPa
to 1099 hPa (standard air pressure at an altitude of 9,100 meters is
around 300 hPa).
Relative air pressure is the one value that is calculated back to sea level
from the local absolute air pressure and can thus be taken as a refer-
ence for weather condition and weather development for the entire
country. It can be programmed to represent your local surroundings.
Since the relative air pressure is also the one value given by various
newspapers, TV and radio broadcasting stations in their daily weather
forecasts for their respective locations, users can set the relative air
pressure of the weather station to this value to represent readings your
their area (see Basic Programming Modes below).
Weather Data (LCD Section 3)
Indoor temperature and humidity are displayed simultaneously in this
section. Use the DISPLAY key to toggle through the displays for other
weather information:
- Outdoor temperature/humidity
- Outdoor wind chill
- Outdoor dew point
- Rainfall 24h
- Rainfall 1h
- Rainfall total.
