additional
sensor
alarm
you

If

connect
to

to
report
the
tripped
alarm.
A
red
alarm
symbol
appears
next
to
that
sensor
in
HOBOlink
when
it
trips.
An
alarm
symbol
will
also
appear
on
the
LCD.
Alarms
for
HOBOlink
calculated
channels
(such
as
dew
point)
are
checked
at
the
connection
interval
for
the
station.
This
is
because
calculated
channels
are
generated
from
data
uploaded
at
each
connection
interval.
Accumulated
rain
alarms
are
triggered
by
the
station
as
soon
as
the
alarm
conditions
are
met.
The
alarm
will
remain
tripped
for
one
accumulation
interval
after
the
trip.
For
example,
if
you
set
the
alarm
to
trip
for
2
inches
of
rainfall
accumulated

hours,
