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 cha nge 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 rain.
Note:
After setting up, readings for weather forecast 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 an
more accurate forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather f orecasting 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. 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 first floor of a house), remove the batteries and re -insert them after about 30
seconds. 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. Again, disregard weather forecasts for the next 12 to 24 hours as
this will allow time for operation at a constant altitude.
THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weather tendency indicators (located on the left and right hand side 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 we ather 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.
LCD2- RADIO CONTROLLED TIME:
The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch Technische
Bundesanstalt Braunschweig which has a time deviation of less than one second in one million years. The time is coded
and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of
approximately 1,500 km. Your radio-controlled Weather Station receives this signal and converts it to show the precise
time in summer or wintertime.
The quality of the reception depends greatly on the geographic location. In normal cases, there should be no reception
problems within a 1500km radius of Frankfurt.
Once the
indoor temperature
and humidity
are
displayed on the Weather Station
during initial set-up
, the DCF tower
icon in the clock display will start flashing in the upper left corner. This indicates that the clock has detected that there is
a radio signal present and is trying to receive it. When the time code is received, the DCF tower becomes permanently
lit and the time will be displayed.
