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 48-60 hours shall be
discarded.

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. Then the second record will be on 18:00 and so
on.
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. 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.
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.
