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 hours. By doing this, the Weather Station will not mistake the
new location as being a possible change in air-pressure when really it is due to the slight change of
altitude.
WEATHER TENDENCY INDICATOR
Working together with the weather icons is the weather tendency indicators (located on the left and
right sides of the weather icons). When the indicator points upwards, it means that the air-pressure
is increasing and the weather is expected to improve, but when indicator points downwards, the
air-pressure is dropping and the weather is expected to become worse.
Taking this into account, one can see how the weather has changed and is expected to change.
For example, if the indicator is pointing downwards together with cloud and sun icons, then the last
noticeable change in the weather was when it was sunny (the sun icon only). Therefore, the next
change in the weather will be cloud with rain icons since the indicator is pointing downwards.
