WEATHER TENDENCY SENSITIVITY 

in the manual settings 

above. 
 

The displayed icon 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 set 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. 75% accuracy is comparable to the best 
meteorological forecasting rate. 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 stable 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. 
 

W EATHER TENDENCY IND ICATOR 

 
Working together with the weather icons is the weather tendency indicators (

arrows 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 the 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, either 

the upward or downward tendency arrow will be displayed until the tendency changes again. 
 

AIR PRESSURE HISTORY GRAP H 

 
The LCD shows the relative air pressure value and the air pressure history on a bar graph. 
Press the SET button 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, -8, -
6, -3 and 0 hour). 

 

Mode 2

: The bar graph displays the air pressure history of the past 72 hours in seven steps. 

The horizontal axis represents the last 72 hours of air pressure recording (-72, -48, -36, -24, 
-12, -6 and 0 hour).
