Note:
-
The weather forecast is reflecting the weather situation for next 12 hours, it may not
necessarily reflect the current situation.
-The “Snowy” icon will be displayed when the outdoor temperature is below -3°C (26°F), and
under cloudy or rainy forecast .
BAROMETRIC PRESSURE
The barometric pressure window (
BARO
) locates in the middle right of 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 and select the wind display mode
1 . In normal mode, press
[ BARO ]
key to change the barometer unit in this sequence: hPa
→
inHg
→
mmHg
2 . In normal mode, press and hold
[ BARO ]
key to switch between
ABSOLUTE/RELATIVE
display .
Absolute
The absolute atmospheric pressure of your location .
Relative
The relative atmospheric pressure based on the sea level
To set the RELATIVE atmospheric pressure value
1 . Obtain the atmospheric pressure data of the sea level (it is also the relative atmospheric
pressure data of your home area) through the local weather service, internet or any weather
information source .
2 . In normal mode, press and hold
[ BARO ]
key for 2 seconds until “
ABSOLUTE
” or
“
RELATIVE
” icon flashes.
3 . Press
[ GRAPH / Λ ]
or
[ °F / °C / V ]
key to switch to “
RELATIVE
” mode .
4 . Press
[ BARO ]
key once again, the “
RELATIVE
” atmospheric pressure digit flashes.
5 . Press
[ GRAPH / Λ ]
or
[ °F / °C / V ]
key to change its value .
6 . Press
[ BARO ]
key to save and exit the setting mode .
Note:
-When you change the RELATIVE atmospheric pressure value, the weather indicators will
change along with it .
-The built-in barometer detects the environmental absolute atmospheric pressure changes .
Based on the data collected, it predicts the weather conditions in the forthcoming 12 hours .
The weather indicator will change according to the detected absolute atmospheric pressure
after operating the clock for 1 hour .
-The RELATIVE atmospheric pressure is based on the sea-level pressure you entered but it
will change with the absolute atmospheric pressure after operating the clock for 1 hour .
