absolute (ABS) pressure and relative (REL) pressure.
Note: The display console displays two different pressures: absolute (measured) and relative
(corrected to sea-level).
To compare pressure conditions from one location to another, meteorologists correct pressure to
sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level
corrected pressure (the pressure your location would be at if located at sea-level) is generally
higher than your measured pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m),
but the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level pressure
around the world. Relative pressure measurements greater than 29.92 inHg (1013 mb) are
considered high pressure and relative pressure measurements less than 29.92 inHg are considered
low pressure.
To determine the relative pressure for your location, locate an official reporting station near you
(the internet is the best source for real time barometer conditions, such as Weather.com or
Wunderground.com), and set your weather station to match the official reporting station.
To calibrate the relative pressure to a local airport, please reference Section 4.5.
4.3 Dew Point
While in normal mode, Press the TEMP/+ key to view the Dew Point in the outdoor temperature
field. If key idle 30 seconds, the display will return to normal mode.
To exit the Dew Point display mode, press the SNOOZE/LIGHT key (on the top of the display
console), or wait 30 seconds for the timeout to take effect.
4.4 Alarms

While in normal mode, press the ALARM key to view the alarm time. The alarm icon will be
displayed in the time field.
4.4.2 Time Alarm Settings Mode
To enter the Alarm Mode, press and hold the ALARM key for two seconds (ALARM + 2
seconds). To advance each command, press (do not hold) the SET key.
