Alarm Mode

4. Use the console keys to select a different weather variable.
The console's time displays time of the selected variable's high or low.
5. Press DONE to exit the Highs and Lows mode. The console screen switches
to the Current Weather mode.
Alarm Mode
The Vantage Pro2 features more than 30 alarms that can be programmed to
sound whenever a reading exceeds a set value. With the exception of
barometric pressure and time, all alarms sound when a reading reaches the
alarm threshold. For example, if the high outside temperature alarm threshold
is set at 65º F, the alarm will sound when the temperature rises to 65.0º F.
When an alarm condition exists, the audible alarm sounds, the alarm icon
blinks repeatedly, and an alarm description appears in the ticker at the bottom
of the screen. The alarm sounds for a maximum two minutes if the console is
battery-powered, but the icon will continue to blink and the message will stay
in the ticker until you clear the alarm or the condition clears. If you're using
the AC adapter, the alarm will continue sounding as long as the condition
exists.
The alarm will sound again for each new alarm. If more than one alarm is
active, the description for each active alarm cycles onto the screen every four
seconds. A "+" symbol appears at the end of the alarm text if more than one
alarm is tripped.
Low alarms work the same way. For example, if the wind chill threshold is set
for 30ºF, the alarm condition begins when the wind chill drops to 30º and will
continue until the wind chill rises above 30º.
Four Special Alarms
ET (Evapotranspiration)
ET is updated only once an hour, on the hour. If during a given hour the ET
Value exceeds the alarm threshold, the ET alarm sounds at the end of that hour.
This is true for daily, monthly, and yearly ET alarms. You must have the
optional Solar Radiation Sensor to use this alarm. See "Evapotranspiration
(ET)" on page 48 for a description of this variable.
Barometric Pressure
The Vantage Pro2 allows you to set two barometric pressure alarms: a "rise"
alarm and a "fall" alarm. You may select any rate of change per three hours
between 0.00 and 0.25 inches (6.35 mm) Hg, (8.5 mb, hPa); the alarm will
sound if the rate of change (in either direction) exceeds the threshold you set.
This alarm is updated every 15 minutes.
Time
The time alarm is a standard "alarm clock" alarm. It sounds for one minute at
the set time. Make sure you choose AM or PM, if you're in 12-hour mode.
