The Weather Monitor II features a set of alarms which can be programmed to
sound whenever a reading passes a particular point. Check the chart below to
determine which functions have alarms and what kind of alarms they have. All
alarms (except barometric pressure, dew point, and time) behave in basically
the same way. The general procedure for displaying and setting alarms is cov-
ered below.
* The time alarm is a standard time alarm, just like the one on any alarm clock.
** Because the change in barometric pressure is generally considered more important than the
barometric pressure itself, there is a special alarm for barometric trend. The procedure for setting
this alarm is covered separately below.
*** Dew point has a special alarm designed to alert you when the temperature comes within 2˚F
(1˚C) of dew point. Refer to the booklet included with the External Temperature/Humidity Sensor
for instructions on using the dew point alarm.
Alarm Conditions
On all high alarms, the alarm is triggered when a reading reaches the alarm
point and will continue to sound until the reading drops below the alarm
point. On all low alarms, the alarm is triggered when a reading reaches the
alarm point and will continue to sound until the reading rises above that point.
The Alarm Display
When the alarm sounds, the console makes a high-pitched beeping sound and
immediately displays the function triggering the alarm. The word ALARM
flashes on and off in the display. The alarm will continue until alarm conditions
are no longer met or the alarm is cleared. You can briefly look at other functions
by pressing the appropriate key(s), but the display will always return to the
alarming function.
