Page 21
Examples of changing weather icons: Note: After initial set up of the intelligent weather station with the setting of the relative value, readings for weather forecasts should be disregarded for the next 12-24 hours. This will allow sufficient time for the intelligent weather station to collect air pressure data at a constant altitude and therefore result in a more accurate forecast.
AIR PRESSURE The fifth section of the LCD shows the relative air pressure and the air pressure history. Air pressure changes in hPa Air pressure over the last 12 hours The reference relative air pressure can be set between 28.35 to 30.72 inHg (960 to 1040hPa).
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 bar to the left. Note: For accurate barometric pressure trend, the intelligent weather station should operate at the same altitude.
