In case of an aneroid barometer with a spiral, there is an adjusting screw on the back. This screw can loosen or increase tension of the spiral.First you need to know the atmospheric pressure in your area, which can be found on meteorological sites. For example: 1005 mbar
(hPa):
change. This equals a rating of 753.8mm. There is an easy conversion method between the two, hPa
/1.333= mm AND mm *1.333= hPa.
(simplified but still very accurate)
Then
just adjust the screw to the right atmospheric pressure on the scale of the barometer, the arrow will be calibrated. (in fact you set the pressure of the vacuum inside the barometer.)
Now every change in pressure will be pointed out by the arrow correctly.
