Push
Button.
Logging
will
end
once
you
press
the
Start/Stop
logging
button
for
3
seconds.
Note
that
if
you
also
choose
Push
Button
to
start
logging,
then
you
will
not
be
able
to
stop
logging
until
30
seconds
after
logging
begins.
If
you
select
the
Push
Button
setting,
then
you
also
have
the
option
to
select
“Allow
button
restart.”
This
allows
you
to
stop
and
then
restart
logging
during
the
deployment
by
pushing
the
Start/Stop
button
on
the
logger
for
3
seconds.
Important:
When
“Allow
button
restart”
is
selected
and
you
use
the
Start/Stop
button
to
stop
and
restart
logging,
logging
will
restart
on
the
next
even
logging
interval,
not
at
the
time
the
button
was
pushed.
For
example,
a
logger
started
logging
at
7:00
AM
with
a
logging
interval
set
to
1
hour.
If
you
press
the
Start/Stop
button
to
stop
the
logger
at
8:45
AM
and
then
press
the
button
again
at
10:15
AM,
logging
will
not
begin
immediately
at
10:15.
Instead,
logging
will
begin
again
at
11:00
AM,
which
is
the
next
even
interval
time
based
on
your
1
‐
hour
logging
interval.
Therefore,
depending
on
the
logging
interval,
the
gap
between
the
time
you
press
the
button
to
resume
logging
and
the
time
actual
logging
begins
could
be
significant.
The
faster
the
logging
interval,
the
less
time
will
elapse
before
logging
resumes.
Specific
Stop
Date.
Logging
will
end
at
a
date
and
time
you
specify.
Note
that
if
you
also
configure
the
logger
for
a
Push
Button
stop
and
to
“Allow
button
restart,”
then
the
logger
will
stop
logging
at
the
date
you
select
regardless
of
how
many
times
you
stop
and
restart
the
logger
with
the
Start/Stop
button.
9.
Choose
whether
to
keep
the
LCD
on
or
off.
By
default,
the
LCD
will
always
remain
on
while
logging.
If
you
select
the
“Turn
LCD
off”
checkbox,
the
LCD
will
not
show
the
current
readings,
status,
or
other
information
while
the
logger
is
logging.
You
will,
however,
be
able
to
temporarily
turn
the
LCD
screen
on
by
pressing
the
Start/Stop
button
for
1
second
if
you
select
this
option.

Click
the
Start

to
launch
the
logger.
Disconnect
the

Logger
).
After
logging
begins,
you
can
read
out
the
logger
at
any
time
(see
Reading

the
Logger
for
details).
Setting
up
Alarms
You
can
set
an
alarm
to
trip
on
the

falls
below
a
specified
value.
To
set
an
alarm:
1.
Click
the
Alarms
button
from
the
Launch
Logger
window.
If
the
Alarms
button
is
disabled,
make

(Alarms
can
only
be

checkbox
or
drag
the

5.
Set
the
duration
before
an
alarm
is
tripped.
6.
Select
either
Cumulative
or
Consecutive.
If
you
select
Cumulative,
then
the
alarm
will
trip
when
the
time
the
sensor
is
out
of
range
over
the
course
of
the
deployment
is
equal
to
the
selected
duration.
If
you
select
Consecutive,
then
the
alarm
will
trip
when
the
time
the
sensor
is
continuously
out
of
range
is
equal
to
the
selected
duration.
For
example,
the
high
alarm
for
temperature
is
set
to
85°F
and
the
duration
is
set
to
30
minutes.
If
Cumulative
is
selected,
then
an
alarm
will
trip
once
a
sensor
reading
has
been
at
or
above
85°F
for
a
total
of
30
minutes
since
the
logger
was
configured;
specifically,
this
could
be
15
minutes
above
85°F
in
the
morning
and
then
15
minutes
above
85°F
again
in
the
afternoon.
If
Consecutive
is
selected,
then
an
alarm
will
trip
only
if
all
sensor
readings
are
85°F
or
above
for
a
continuous
30
‐
minute
period.

Repeat
steps
2
through
6
for
the
other
sensor
if

Choose
how
long
the
logger
should
maintain
a
sensor
alarm

“Host
has
relaunched
logger”
if
you
want
the
alarm
to
remain
visible
on
the
LCD
until
the

time
you

the
logger.
Select
“Sensor
reading
within

if
you
want
the
alarm
to
clear
once
the
sensor
reading
returns
to
the
normal
range
between
the
high
and
low
alarm
