1. Press BAR to select barometric pressure. Barometric
pressure may be displayed in inches (in), millimeters (mm),
millibars (mb) or hectoPascals (hPa). See “Selecting Units of
Measure” on page 26 for more information on changing the
unit measure.
2. Press WxCEN to display the information available for the barometric
pressure trend in the Weather Center.
3. Continue pressing WxCEN to scroll through all the barometric pressure
related Weather Center screens, which include:
• Barometric Pressure Change Per 24 hours — Displays the difference
between the barometric pressure currently recorded and the barometric
pressure recorded at the same time yesterday.
• Maximum Barometric Pressure — Displays the highest barometric pres-
sure reading for the day and the time the measurement was recorded.
• Minimum Barometric Pressure — Displays the lowest barometric pres-
sure reading for the day and the time the measurement was recorded.
• Altimeter Setting — Displays the barometric pressure that would display
if “ALT SETTING” was selected in Screen 11: Barometric Reduction Set-
ting. The barometric pressure reading and the altimeter setting reading
will be the same if the altimeter setting was selected. See “Screen 11: Baro-
metric Reduction Setting” on page 11 for more information.
• Absolute Pressure — Displays the barometric pressure that would dis-
play if “NONE” was selected in Screen 11: Barometric Reduction Setting.
The barometric pressure reading and the absolute pressure reading will
be the same if none was selected. See “Screen 11: Barometric Reduction
Setting” on page 11 for more information.
• Barometric Pressure Trend — Describes the current barometric trend and
the numeric change in the barometric pressure over the last three hours.
The Barometric Pressure Trend listed in the Weather Center corresponds
to the pressure trend arrows displayed next to the Barometric Pressure
variable. The trends are:
• Bar Rising Rapidly — Refers to a rise in pressure greater than or equal
to 0.06'' (2 hPa) over the last three hours.
• Bar Rising Slowly — Refers to a rise in pressure greater than or equal
to 0.02'' (0.7 hPa) but less than 0.06'' (2 hPa) over the last three hours.
• Bar Steady —Refers to no change or a change of less than
0.02'' (0.7 hPa) either rising or falling over the last three hours.
• Bar Falling Slowly — Refers to a fall in pressure greater than or equal
to 0.02'' (0.7 hPa) but less than 0.06'' (2 hPa) over the last three hours.
• Bar Falling Rapidly — Refers to a fall in pressure greater than or equal
to 0.06'' (2 hPa) over the last three hours.
