In
some
applications
(such
as
a
refrigerator,
freezer,
clean
room)
it
may
be
more
convenient
to
permanently
mount
an
external
sensor
at
the
site.
Be
sure
to
place
the
remote
sensor
in
a
location
that
is
representative
of
the
target
measurement
location
and
allows
free
flow
of
air
(beware
of
any
drafts
caused
by
vents,
doors,
etc).
If
you
permanently
mount
the
sensor
and
later
have
to
disconnect
it
from
the
logger
for
readout,
select
Delayed
Launch
when
you
relaunch
the
logger
to
allow
time
to
reconnect
the
sensor
before
the
actual
launch
time.
