RELATIVE AIR PRESSURE UNIT SETTING
The relative air pressure unit can be set in inHg, hPa or mmHg unit. (default unit is inHg).
1.
Use the MAX/+ or MIN/- key to toggle between “inHg”, “hPa” or “mmHg”
2.
Confirm with the SET key and enter the Relative Pressure Value setting.
Note:
The default reference pressure value of the barometer is 29.91 inHg (1013 hPa). 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 present atmospheric pressure of your home area (Local weather service, calibrated instruments in public
buildings, airport).
RELATIVE PRESSURE VALUE SETTING
The default relative pressure value is 29.91 inHg (1013 hPa). This corresponds to the average air pressure. Pressure
below this is referred to as low-pressure area (weather to become worse), pressure above as high-pressure area
(weather to improve). The relative air pressure can be manually set to another value within the range of 28.35 to 30.72
inHg (960 – 1040 hPa or 720 – 781 mmHg) for a better reference.
1.
The current relative pressure value will start flashing
2.
Use the MAX/+ or MIN/- key to increase or decrease the value. Keep holding the key allows the value to advance
faster.
3.
Confirm with the SET key and enter the Language display setting.
Note:
This calibration facility is useful for those users living at various elevations above sea level, but wanting their air
pressure display based on sea level elevation.
