It is widely known that the higher above sea level, the lower the pressure. The higher the pressure, the less changeable the weather. At a pressure higher than 1020 mbar, we can expect a dry, fair day. In summer, this will simply mean pleasant weather; in winter, the day will probably be frosty (though with the possibility of fog). Pressure in the range of 1005–1020 mbar indicates changeable weather. Bright spells may alternate with passing rain. At pressure below 1000 mbar, the sky will be covered with clouds and rain can be expected. A rise in pressure means improvement, and conversely, a fall means worsening weather. Sudden, significant pressure jumps in summer may indicate severe storms.

A barometer is a very precise device that measures air pressure. For this purpose, it uses a so-called vacuum capsule, whose walls expand or contract by hundredths of a millimeter depending on changing air pressure.

The barometer was calibrated at the factory. However, as a result of, for example, strong shocks, a new adjustment may prove necessary. To carry it out, use a screwdriver and adjust the screw on the rear wall of the device in accordance with the recommendations in the enclosed instructions.
