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.
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;

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. (rain data information
only available if a rain sensor is being used- optional).
