WEATHER FORECAST AND WEATHER TENDENCY:
WEATHER FORECASTING ICONS:
Weather icons in the third section of LCD can be displayed in any of the
following combinations:
Sunny Cloudy with sunny intervals Rainy
For every sudden or significant change in the air pressure, the weather
icons will update accordingly to represent the change in weather. If the
icons do not change, then it means either the air pressure has not changed
or the change has been too slow for the Weather station to register.
However, if the icon displayed is a sun or raining cloud, there will be no
change of icon if the weather gets any better (with sunny icon) or worse
(with rainy icon) since the icons are already at their extremes.
The icons displayed forecasts the weather in terms of getting better or
worse and not necessarily sunny or rainy as each icon indicates. For
example, if the current weather is cloudy and the rainy icon is displayed, it
does not mean that the product is faulty because it is not raining. It simply
means that the air pressure has dropped and the weather is expected to
get worse but not necessarily rainy.
Note:
After setting up, readings for weather forecasts should be disregarded for
the next 12-24 hours. This will allow sufficient time for the Weather station
to collect air pressure data at a constant altitude and therefore result in a
more accurate forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed.
The weather forecasting feature is estimated to have an accuracy level of
about 75% due to the varying areas the Weather station has been
designed for use. In areas that experience sudden changes in weather (for
example from sunny to rain), the Weather station will be more accurate
compared to use in areas where the weather is stagnant most of the time
(for example mostly sunny).
If the Weather station is moved to another location significantly higher or
lower than its initial standing point (for example from the ground floor to the
upper floors of a house), discard the weather forecast for the next 12-24
