[. . . ] FAMILY WEATHER STATION Instruction Manual INTRODUCTION: Congratulations on purchasing this state-of-the-art weather station as an example of excellent design and innovative measuring technique. Featuring time, date, calendar, weather forecast, wind direction and speed, rainfall, outdoor temperature and outdoor humidity, air pressure and various alarm settings for different weather conditions, this weather station will provide you with various weather information and weather forecast. Pages after pages, you will discover that the operation of your weather station is really simple !« Instant Transmission+» is the up and coming state-of-the-art new wireless transmission technology, exclusively designed and developed by LA CROSSE TECHNOLOGY. [. . . ] So you may adjust the "sensitivity" of the pressure change checking in the setting mode ­see WEATHER TENDENCY THRESHOLD 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 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 station has been designed for use. 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 upper floors of a house), discard the weather forecast for the next 12-24 hours, as the Weather Station 31 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 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. 32 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 hPa (+4, +2, 0, -2, -4. [. . . ] To wall mount, use the 2 screws to affix the wall bracket to the desired wall, plug in the thermo-hygro sensor to the bracket and secure both parts by the use of the supplied screw and ensure that the cables from the wind and rain sensors are correctly plugged in otherwise data transmission errors could occur. 47 The Wind Sensor Wind vane Vertical mast Wind fan Horizontal panel Firstly, check that the wind-fan and the wind-vane can rotate freely before fixing the unit. For correct and accurate readings it is important to mount the sensor so that the front (marked E) is pointing in East-West direction. The wind sensor should now be mounted using the screw or cable tie provided onto a solid wall/ panel mast or mast to allow the wind to travel around the sensor unhindered from all directions (ideal mast size should be from diameter 16mm to 33mm). Once the wind sensor is fixed onto the mast, connect the cable to the corresponding thermo-hygro sensor socket so that operating power supply can be received and data can be transmitted to the base station. 48 The Rain Sensor For best results, the rain sensor should be securely mounted onto a horizontal surface about 1 meter above the ground and in an open area away from trees or other coverings where rainfall may be reduced causing inaccurate readings.
