The Cape Cod Marine Barometer features a precision, German-made, aneroid movement
housed in a solid brass case. The temperature-compensated movement is designed for use at
altitudes from sea level up to 2,000 feet.
further adjustment will ever be needed, unless it is relocated to a different altitude.
The exact reading is not critical; much more important is whether the barometer is
rising or falling, and how fast that change is occurring.
After setting the barometer, attach it to the wall or
mounting surface by drilling three small holes,
aligned with the holes in the brass case, then attach
the barometer with the three brass wood screws.
Operation: Barometers measure air pressure by one
of several means. By far the most common type is the
"aneroid" barometer, which uses an air-tight chamber
and a series of levers and linkages to record changes
in pressure. As the air pressure changes, the chamber
expands or contracts, moving the levers, which in
turn rotate the black pointer up or down the dial. The

Cape Cod Marine Barometer uses this highly
accurate method.

Installation and Operation
Installation: The barometer is attached to the
wall, or a wooden plaque if desired, using the
three brass wood screws enclosed. Before
mounting, the movement should be set to
compensate for your altitude by turning the
set-screw on the back with a small screw
driver. The barometer is set at the factory for
the reading at sea level, so if you are located at
or slightly above (<100 feet) sea level, little or
no adjustment should be necessary.
To set the barometer, obtain the current
barometer reading from your local weather
forecast or from one of the many web sites
devoted to weather, then turn the set-screw
until the black pointer matches that reading.
Once the barometer has been properly set, no
