Screen 10: Elevation
Your station’s elevation is used in
determining your barometric
pressure. Meteorologists
standardize barometric pressure
data to sea level so that surface
readings are comparable, whether
they are taken on a mountainside or by the ocean. To use this same
standardization and ensure consistent readings, enter your elevation in this
screen.
If you do not know your elevation, there are several ways to find out. Many
atlases and almanacs include elevation for cities and towns. You can also check
with the reference department of your local library, or use Google Maps (in
“terrain” view).
The more accurate you are, the better; but a reasonable estimate works too.
1. Press the < and > keys to move from one value to another.
2. Press the + and - keys to adjust a numeral up or down.
3. To switch between feet and meters, press 2ND then press UNITS.
4. If your location is below sea level, such as in Death Valley or the Salton Sea,
first enter the elevation as a positive number. Select the “0” immediately to
the left of the left-most non-zero digit (the second zero from the left in 0026,
for example, or the first zero from the left in 0207) and press and hold the +
or - key until it cycles from 0 to 9 and then
-.
Note: You can only set the elevation to negative after you have entered a non-zero digit and
when the zero in the position immediately to the left of the left-most non-zero digit has
been selected. If you need to enter an elevation below -999 feet, select meters and enter
the converted number (multiply your elevation in feet by 0.3048).
5. Press DONE to move to the next screen.
Screen 11: Barometric Reduction Setting
The Barometric Reduction Setting screen indicates the method by which
barometric pressure is to be determined and calculated. The factory default is
NOAA, but in this screen you may select a different method.
