Setting the Sea Level
Barometric Pressure
No matter where you are, barometric pres-
sure is measured using the current sea level
barometric pressure. This way, meteorolo-
gists (and you!) can easily compare mea-
surements from locations at different
altitudes.
Note: To obtain the current sea level baro-
metric pressure in your area, contact the
nearest airport or go to http://
www.nws.noaa.gov and select current
weather conditions for the closest location to
you in your state.

Using the Barometric
Pressure-Drop Alarm
You can set the monitor to sound an alarm
when the current barometric pressure drops
to the condition relevant to a programmed
setting. For example, you can set the monitor
to sound an alarm if the current barometric
pressure drops .03 inch below the level you
specify. Each time the barometric pressure
changes and meets the set condition,

flashes and the monitor sounds an alarm for
about 1 minute. To silence the alarm sooner,
press any key.
Note: If you press a key to silence the alarm,
the alarm stops sounding, but
continues
to flash until the alarm condition is no longer
met.
To view the current barometric pressure-
drop alarm setting, press
