[. . . ] 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 pressure and the weather is expected to get worse from the present time "0". At every full hour, the current air pressure is used as a basis for the display of a new graph bar. The existing graph is then moved one column to the left. Note: For accurate barometric pressure trend, the Weather Center should operate at the same altitude. Should the unit be moved, for instance from the ground to the second floor of the house, the readings for the next 48-60 hours shall be discarded. . WIND SPEED MEASUREMENT In normal display mode, the second section of the LCD shows the following wind data. Wind chill in F or C Wind Speed in km/h, mph or m/s Gust in km/h, mph or m/s (displayed when in Mode 2, by pressing the SET key shortly) Wind chill Wind speed or Gust will be shown 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. 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 scale on the right compares the result. The "0" in the middle of this scale determines the current air pressure. RAINFALL MEASUREMENT (OPTIONAL) 22 21 The total rainfall and 24 hour rainfall measurement is displayed in the last section of the LCD (where pressure is normally displayed), in the unit of mm or inch. To View the 24-hour rainfall or the Total rainfall reading: 1. In normal display, press SET key once and the display will shift to Mode 2. Press + key consecutively key to toggle between the 24-hour rainfall, Total rainfall and Rel. pressure reading. To view the weather history: 1. In normal display, press the HISTORY key. The latest weather record will be shown with the date and time of recording. The "HISTORY" icon will be displayed at the bottom of the LCD. When viewing History records, user may shift to see the Mode 1 or Mode 2 data by pressing the SET key. Mode 1: with wind speed + outdoor Temp + Rel. pressure; Mode 2: with wind gust + Dew point + rainfall data (optional) Note: To view total rainfall or 24-hour rainfall in history records, first, in normal display mode, choose to show the particular rainfall data, then press the History key followed by the SET key to view the particular rainfall data in History records.
