Your barometer is a useful instrument for weather prediction. The settable
pointer, controlled by the knob in the center of the glass lens, is used to show
changes in atmospheric pressure. When reading your barometer, lightly tap
the case to take up normal slack in the linkage. Next, move the settable
pointer until it rests exactly over the movement pointer. The next time you
observe your barometer lightly tap the case again and you will now have
a clear indication of rising, falling, or steady barometric pressure. Observation
of changes in barometric pressure, wind and temperature conditions give the
weather watcher a strong basis for forcasting the weather.
