To forecast the weather, you can set the wind direction and align the central disc with the steel pointer on the dial. Adjusting the altitude correction involves rotating the rear cover until the arrow lines up with the appropriate level on the scale engraved on the side of the case. By considering whether the pressure has been rising, falling, or remaining steady, along with the season (summer or winter), you can read the letter that appears within the corresponding sector in the center of the dial. A detailed description of its operation can be found on page 89 of Banfield's book "BAROMETERS Aneroid and Barographs", with an illustration on page 87.
