WEATHER FORECAST
The built-in barometer continually monitor atmosphere pressure. 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.
Sunny Partly cloudy Cloudy
Rainy Rainy / Stormy Snowy
NOTE:
- The accuracy of a general pressure-based weather forecast is about 70% to 75%.
- The weather forecast is reecting the weather situation for next 12~24 hours, it may not necessarily
reect 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
aected by weather, it is possible to forecast the weather by measuring
the changes in pressure.
TO VIEW THE BAROMETRIC PRESSURE IN DIFFERENT UNIT
1. In normal mode, press and hold [ BARO ] key with 2 seconds enter unit setting mode.
2. Press [
] or [ ] key to change the unit in sequence: hPa → inHg → mmHg
TO SELECT ABSOLUTE OR RELATIVE BAROMETRIC PRESSURE MODE
In normal mode, press [ BARO ] key to switch between ABSOLUTE / RELATIVE barometric pressure.
RAIN
The RAINFALL section shows the rainfall or rain rate information.
TO SET THE RAINFALL UNIT
1. In normal mode, press and hold [ RAIN ] key for 2 seconds to enter unit setting mode.
2. Press [
] or [ ] key to toggle the unit between mm and in (rainfall) or mm/h and in/h
(rain rate).
3. Press [ RAIN ] key to conrm 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 (default)
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
Period of rainfall
6. Rate - Current rainfall rate (base on 10 min rain data)
