The following is a guide for preparation, care and operation of your marine weather instrument.

Note: Some of the images are generic and may not match your exact model.

2. Care and Cleaning

Avoid use of harsh household cleaners and coarse paper towels, which can scratch the bezel or lens.

Fingerprints and dirt may be removed the lenses and bezels with a soft cloth lightly dampened with a

mixture of water and mild dishwashing liquid. Be sure to dry the lens and bezel with a soft cloth

after cleaning.

3. Barometer Operation

3.1 How the aneroid barometer works

An aneroid barometer uses a small, flexible metal box called an aneroid cell. This aneroid capsule

(cell) is made from an alloy of beryllium and copper. The evacuated capsule is prevented from

collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or

contract. This expansion and contraction drives mechanical levers such that the tiny movements of the

capsule are amplified and displayed on the face of the aneroid barometer. This model includes a

manually set gold needle which is used to mark the current measurement so a change can be seen. It

was invented by Blaise Pascal.
