e) Weather forecast and weather tendency
The display shows one of the following three combinations of weather icon and trend arrow:
Sunny
Partly cloudy
Rainy
Weather forecast
In case of sudden or larger air pressure fluctuations, the display symbols are updated to indicate
the weather change. If the display symbols do not change, either the air pressure has not
changed or the change occurred so gradually that it could not be registered by the weather
station.
If sunny weather is indicated and the weather improves, the display will not change. If rainy
weather is indicated and the weather worsens, the display will also not change as both display
icons already represent the two extremes.
The display symbols indicate an improvement or worsening of the weather. This does not
necessarily mean that the weather is sunny or rainy. If the weather is cloudy, although the
weather station indicates rain, this is not a malfunction. It only means that the barometric
pressure has dropped and the weather is likely to worsen. But this need not necessarily mean
rain.
Within the first 24 hours after start-up, the weather forecast is not reliable. The weather station
must first collect barometric pressure data at a constant altitude to make a more exact forecast.
As with all other weather forecasts, absolute accuracy cannot be guaranteed for this weather
station. The reliability of the weather forecast is approx. 75%. In areas with fast-changing
weather conditions, the weather forecast will be slightly more accurate in comparison to areas
with constant weather.
