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 48-60 hours shall be discarded..
WIND SPEED MEASUREMENT
In normal display mode, the second section of the LCD shows the following wind data.

VIEW 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. Then the second record will be on
18:00 and so on.
Each weather record includes the Wind direction, Wind speed/ gust, 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. Also, the time and date of recording will be displayed.
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.

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.
