WEATHER FORECAST
The built-in barometer can notice atmosphere pressure changes. Based on the data collected, it can
predict the weather conditions in the forthcoming 12~24 hours within a 30~50km (19~31 miles) radius.
NOTE:
- The accuracy of a general pressure-based weather forecast is about 70% to 75%.
- The weather forecast is reflecting the weather situation for next 12~24 hours, it may not necessarily
reflect the current situation.
- The SNOWY weather forecast is not based on the atmospheric pressure, but based on the temperature
of outdoor. When the temperature is below -3°C (26°F), the SNOWY weather icon will be displayed on
the LCD.
BAROMETRIC PRESSURE
The atmospheric pressure is the pressure at any location of the earth caused by the weight of the
column of air above it. One atmospheric pressure refers to the average pressure and gradually
decreases as altitude increases. Meteorologists use barometers to measure atmospheric pressure.
Since variation in atmospheric pressure greatly affected by weather, it is possible to forecast the weather
by measuring the changes in pressure.
TO SET THE BAROMETER UNIT
In normal mode, press [ BARO UNIT ] key to change the barometer unit in this sequence: hPa → inHg
→ mmHg
TO VIEW THE ABSOLUTE / RELATIVE BAROMETRIC READING
In normal mode, press [ BARO ] key to switch between ABSOLUTE / RELATIVE barometric reading.
RAINFALL
The RAINFALL section shows the rainfall and rain rate information
TO SET THE RAINFALL UNIT
1 . Press and hold [ RAIN ] key for 2 seconds to enter unit setting mode.
2 . Press [ Ʌ ] or [ V ] key to toggle the rainfall unit between mm and in. 3 . Press [ RAIN ] key to confirm
and exit the setting.
TO SELECT THE RAINFALL DISPLAY MODE
Press [ RAIN ] key to toggle between:
1. HOURLY - the total rainfall in the past hour
2. DAILY - the total rainfall from midnight
3. WEEKLY - the total rainfall of the current week
4. MONTHLY- the total rainfall of the current calendar month
5. Total - the total rainfall since the last reset 6. Rate - Current rainfall rate in past an hour (Update every
24 seconds)
TO RESET THE TOTAL RAINFALL RECORD
In normal mode, press and hold [ HISTORY ] key for 2 seconds to reset all the rainfall record.
