RELATIVE AIR PRESSURE UNIT SETTING
The relative air pressure can be set as inHg or hPa. The default unit is hPa.
1. The relative air pressure unit is flashing.
2. Press the ▲UP ARROW key or ▼DOWN ARROW
key to toggle between the unit “inHg" or “hPa”
3. Press the SET key to confirm and to enter the
RELATIVE PRESSURE REFERENCE VALUE
SETTING
.
RELATIVE PRESSURE REFERENCE VALUE SETTING
Note:
The default reference pressure-value of the barometer is 1013 hPa when
batteries are first inserted.
For an exact measurement, it is necessary to first adjust
the barometer to your local relative air pressure (related to elevation above sea
level)
. Ask for the current atmospheric pressure of your home area (Local weather
service, the world wide web, optician, calibrated instruments in public buildings, airport).
Note:
This feature is useful for those who live at elevations above sea level, but
want their air pressure display to be based on sea level elevation.
The relative air pressure can be manually set to another value within the range of 920 to
1080 hPa (27.10 to 31.90 inHg) for a better reference.
1. The current relative pressure value will start flashing
2. Press the ▲UP ARROW key or ▼DOWN ARROW
key to increase or decrease the value. Continually
holding the key will allow the value to increase faster.
3. Press the SET key to confirm and to enter the
WEATHER TENDENCY SENSITIVITY VALUE
SETTING
.
WEATHER TENDENCY SENSITIVITY LEVEL SETTING
Set the switching sensitivity value, 2,3 or 4 hPa (.06, .09, or .12 inHg) for the change in
the display of weather icons. This represents the "sensitivity" of the weather forecast
(the smaller the value selected, the more sensitive the weather forecast). The default
value is 3 hPa. Select lower numbers for high humidity areas, i.e. Oceanside. Select
high numbers for arid areas, i.e. desert.
