RELATIVE PRESSURE REFERENCE VALUE SETTING
Note:
The default reference pressure value of the barometer is 29.91inHg 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, www, optician, calibrated instruments in public buildings, airport).
The relative air pressure can be manually set to another value within the range of 27.17 to 31.90 inHg (919 to 1080 hPa) for a better reference.
