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 48-60 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 Center has been designed for use. In areas that experience
sudden changes in weather (for example from sunny to rain), the Weather Center 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 Center 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 48-60 hours, as the Weather Center may
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 (arrow
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.
Note: Once the weather tendency indicator has registered a change in air pressure,
it will remain permanently visualized on the LCD.
AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC
PRESSURE TREND)
The LCD also shows the relative air pressure value and the air pressure history.
Press the SET key to toggle between Mode1 and Mode2 of the display.
• Mode 1: the bar graph displays the air pressure history of the past 24 hours in
seven steps. The horizontal axis represents the last 24 hours of air pressure
recording (-24, -18, -12, -9, -6, -3 and 0 hour).
