[. . . ] Note: Once the weather tendency indicator has registered a change in air pressure, it will remain permanently visualized on the LCD. WEATHER FORECAST AND WEATHER TENDENCY WEATHER FORECASTING ICONS: Weather forecasting icons are displayed in any of the following combinations at the right bottom part of LCD: TENDENCY TENDENCY TENDENCY 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. (Every time a new average pressure value has been obtained (once per minute), this value is compared with an internal reference value. If the difference between these values is bigger than the selected weather tendency sensitivity, the weather-icon changes, either for worse or for better. In this case, the current pressure value becomes the new weather tendency reference. ) If the icons do not change, either the air pressure has not changed or the change has been too small for the Weather Center to register. So you may adjust the "sensitivity" of the pressure change checking in the setting mode ­see WEATHER TENDENCY SENSITIVITY VALUE SETTING above. 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 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 AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC PRESSURE TREND) The bottom section of the LCD also shows the relative air pressure value and the air pressure history. Depending on programming conditions, display of the history of air pressure in form of a graph consisting of vertical bars. The bar graph of the electronic barometer shows the air pressure history of the past 12 hours in five 3-hour steps. Air pressure changes in inHg Air pressure changes in hPa The horizontal axis represents the last 12 hours air pressure recording (-12, -9, -6, -3 and 0 hour). The bars are plotted at each of the 5 steps and give the trend over the recorded period. The "0" in the middle of this scale determines the current air pressure. The vertical axis represents the air pressure changes in inHg (+0. 12, +0. 06, 0, -0. 06, -0. 12. The newly measured pressure was compared to the previously recorded pressure reading. The pressure change is expressed by the difference between the current ("0h") and the past readings in division of ±2 hPa or ±0. 06 inHg. If the bars are rising it indicates that the weather is getting better due to an increase in air pressure. If the bars go down it indicates a drop of the air 88 89 pressure and the weather is expected to get worse from the present time "0".
