Description
This
is
an
example
of
a
temperature
reading.
Temperature
units
are
determined
by
the
settings
in
HOBOware.
To
switch
between
Celsius
and
Fahrenheit,
change
the
Display
Preferences
in
HOBOware
before
launching
the
logger.
This
is
an
example
of
an
RH
reading.
The
logger
has
been
configured
to
start
logging
on
a
particular
date/time.
The
display
will
count
down
in
days,
hours,
minutes,
and
seconds
until
logging
begins.
In
this
example,
5
minutes
and
38
seconds
remain
until
logging
will
begin.
The
launch
settings
are
being
loaded
onto
the
logger
from
HOBOware.
Do
not
disconnect
the
USB
cable
during
this
process.
An
error
occurred
while
loading
the
launch
configurations
onto
the
logger
from
HOBOware.
Make
sure
the
USB
cable
is
connected
to
both
the
logger
and
the
computer
and
try
launching
again.
The
logger
has
been
stopped
with
HOBOware
or
because
the
memory
is
full.
Notes:
You
can
disable
the
LCD
screen
when
logging.
Select
“Turn
LCD
off”
when
setting
up
the
logger
as
described
in
the
next
section.
When
this
option
is
enabled,
you
can
still
temporarily
view
the
LCD
screen
by
pushing
the
Start/Stop
button
for
1
second.
The
LCD
will
then
remain
on
for
10
minutes.
The
LCD
screen
refreshes
every
15
seconds
regardless
of
the
logging
interval
selected
in
HOBOware.
If
you
choose
a
logging
interval
less
than
15
seconds,
the
data
will
be
recorded
at
the
faster
interval,
but
the
sensor
readings
will
only
be
updated
on
the
screen
every
15
seconds.
When
the
logger
has
stopped
logging,
the
LCD
screen
will
remain
on
until
the
logger
is
offloaded
to
a
computer
or
HOBO
U
‐
Shuttle
(unless
launched
with
the
“Turn
LCD
off”
option).
Once
the
logger
has
been
offloaded
and
disconnected
from
the
computer,
the
LCD
will
turn
off
automatically
after
2
hours.
The
LCD
will
turn
back
on
the
next
time
the
logger
is
connected
to
the
computer.
