[. . . ] 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 pressure and the weather WEATHER TENDENCY INDICATOR Working together with the weather icons is the weather tendency indicators (located on the left and right sides of the weather icons). When the indicator points upwards, it means that 19 20 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. 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. 24 hour rainfall icon 24 hour rainfall amount Total rainfall icon Total rainfall amount 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 VIEWING THE HISTORY DATA The weather station can store up to 140 sets of weather data which are recorded automatically at 3-hour intervals after the weather station is powered up, at the nearest time of 0:00, 03:00, 06:00, 09:00, 12:00, 15:00, 18:00 and 21:00. For instance, if user has manually set the time as 14:52 after installing batteries, the first history record will be made at the coming 15:00 automatically. Each weather record includes the Wind direction, Wind speed/ gust in Beaufort scale, Wind chill temperature, wind speed/gust, dew point, Outdoor temp and humidity, relative pressure, 24-hour rainfall and total rainfall, pressure history and weather tendency. Note: In order to acquire the correct time of recording of the history records, you shall manually set the current time as soon as installing batteries to the weather station. Afterwards, you should avoid changing the pre-set time as it will also alter the recorded "time of recording" of each history record, which may lead to confusion. RAINFALL MEASUREMENT (OPTIONAL) The total rainfall and 24 hour rainfall measurement is displayed in the last section of the LCD, in the unit of mm or inch. 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. 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. pressure; Mode 2 : with wind gust + Dew point + rainfall data (optional) 21 22 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.
