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
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
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 is in the form of a graph consisting of vertical bars.
The bar graph of the electronic barometer shows the air pressure history of the past 12 hours in five

VIEWING THE HISTORY DATA
The weather station can store up to 140 sets of weather data which are recorded automatically at
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,
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
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.
2.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)

compares the result. 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,
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. For example, it should not be moved. Should the unit be moved, for instance from the ground to the second floor of the house, the readings for the next
Note:
The bar graph will scroll right to light regularly to prevent LCD burnout.
WIND DIRECTION AND WIND SPEED MEASUREMENT
In normal display mode, the second section of the LCD shows the following wind data.
•Wind direction (shown on the a compass scale of 16 divisions) and wind speed/ gust in Beaufort scale
•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)
