[. . . ] Press the SET key to switch on or off the alarm. (The showing of the icon ((( ))) means that the alarm is switched on. ) 30 4. Press the ALARM key once to return to the normal display mode. In case the wind speed exceeds the condition for high wind speed alarm, the value will be flashing, along with the corresponding high alarm icon ("HI AL"). User may press any key to stop the sound. HYSTERESIS To compensate for fluctuation of the measured data, which may cause the weather alarm to sound constantly if the measured reading is close to your set level, a hysteresis function has been implemented for each weather alarm. For example, if the high temperature alarm is set to +77°F and the current value moves to +77°F, the alarm will be activated (if it has been enabled). Now when the temperature drops to +76. 8°F or below and thereafter again increases to beyond +77°F, the data will be blinking, but no alarm will be activated. It has to drop to below +75. 2°F (with a pre-set hysteresis of 1. 8°F) so that the alarm can be produced again. Hysteresis values for the various weather data types are given in the following table: Weather data Temperature Humidity Wind speed Hysteresis 1. 8°F 3% RH 3. 1 mph Note: The temperature or humidity data will keep on flashing even after a key has been pressed to stop the alarm or buzzer has been switched off, to indicate that the current weather condition is out of the pre-set limit(s) 31 WEATHER FORECAST AND WEATHER TENDENCY WEATHER FORECASTING ICONS: Weather forecasting icons is 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. 32 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 1224 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. 33 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.
