g) Weather Forecast
The weather station calculates a weather forecast for the next 12 - 24 hours from the barometric
pressure development of the last hours/days. The accuracy that can be achieved with this
technology is at about 70%.
Note:
• The display does not indicate the current weather situation, but a forecast for the next 12 to
24 hours.
• If “sunny” is displayed at night, it means a starry night.
• Calculation of weather forecasts only based on barometric pressure leads to a maximum
accuracy of about 70%. The actual weather at the next day may be completely different.
Since the barometric pressure measured only applies for an area with a diameter of approx.
50 km, the weather may also change quickly. This particularly applies in mountain or high
mountain areas.
Therefore, do not rely on the weather station’s forecast but gather information on site, e.g.
for mountain tours.
• At sudden or larger fluctuations of barometric pressure, the display symbols are updated to
show weather changes. If the display symbols do not change, either the barometric pressure
did not change or the change is so slow that it could not be registered by the weather station.
• If the forecast “sunny” or “rain” appears, the display does not change even if the weather
improves (display “sunny”) or deteriorates (display “rain”), since the displayed symbols
already represent the two extremes.
The display symbols indicate a weather change for the better or worse, which does not have
to mean sun or rain, however, as indicated by the symbols.
• After first insertion of the batteries, disregard the weather forecasts for the first 12 to 24 hours,
because the weather station first has to collect barometric pressure data in this period at a
constant height to make a more exact forecast.
• If the weather station is taken to a site at a much higher or lower altitude than the original one
(e.g. from the ground floor to an upper floor of a house), the weather station may consider
this a weather change.
