Alarm Mode
The Vantage Pro2 features more than 30 alarms that can be programmed to sound
whenever a reading exceeds or drops below a set value. With the exception of baromet-
ric pressure and time, all alarms sound when a reading reaches the alarm threshold. For
example, if the high outside temperature alarm is set at 65º F, the alarm sounds when
the temperature rises to 65.0º F.
When an alarm condition exists, the audible alarm sounds, the alarm icon blinks repeat-
edly, and an alarm description appears in the ticker at the bottom of the screen. The
alarm sounds for a maximum of two minutes if the console is battery-powered, but the
icon continues to blink and the message stays 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 “+” sym-
bol 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 46. 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.
