into
the
SD
card
slot
at

The
card
must
be

If
the

is
being
used
for
the
first
time
it
is
recommended
that
the
card
be
formatted
and
the
logger’s
clock
set
to
allow
for
accurate
date/time
stamping
during
datalogging
sessions.
Refer
to
the
Setup
Mode
section
for
SD
card
formatting
and
time/date

formats
differ.
The
data
on
the
SD
card
can
be
formatted
for
either
format.
The
meter
defaults
to
USA
mode
where
a
decimal
point
is
used
to
separate
units
from
tenths,
i.e.
20.00
.
The
European
format
uses
a
comma,
i.e.
20,00
.
To
change
this
setting,
refer
to
the
Setup
Mode
section.
