Wf
‐
This
selection
saves
waveforms
displayed
on
petMAP
to
the
SD
card.
Waveforms
are
saved
as
.wav
files
that
can
be
viewed
on
a
PC.
Wf+
This
selection
is
identical
to
Wf
‐
but,
in
addition,
will
automatically
save
screen
after
each
BP
determination.
NOTE:
The
above
two
settings
(Wf
‐
and
Wf+)
are
only
useful
for
petMAP
units
that
generate
waveforms,
so
they
would
not
apply
to
gII
units.
File
Name
Format
for

Screen
.JPG
Files
When
the
screen
is
saved
to
the
SD
card,
the
file
name
is
constructed
by
using
the
date
and
time
that
the
screen
was
saved
and
the
file
was
created
and
written
to
the
SD
card.
The
file
name
format
is
MonthDayHoursMinutes,
where
the
months
are
represented
by
the
numbers
1
‐
9
for
January
‐
September,
and
‘O’
for
October,
‘N’
for
November,
and
‘D’
for
December,
and
the
hours
and
minutes
are
each
2
digits
numbers.
For
example,
a
screen
saved
on
April
14
at
2:18pm
would
be
named:
4141418A
.
JPG
The
‘A’
is
appended
to
signify
that
this
is
the
first
screen
saved
during
the
date
and
time
of
4141418.
If
the
user
saves
the
screen
again
during
the
time
4141418
(ie,
during
the
very
same
minute),
the
screen
image
would
be
saved
with
the
file
name
4141418B
.
JPG,
and
then
4141418C
.
JPG
and
so
forth.
In
this
way,
multiple
screen
images
can
be
saved
and
uniquely
named
within
the
same
minute
if
desired.
As
another
example,
if
the
date
and
time
of
the
screen
save
is
December
9
at
8:30
am,
the
file
name
would
be
D090830A.JPG.
As
with
the
.txt
files,
since
the
year
is
not
a
part
of
the
file
name,
if
multiyear
retention
of
the
saved
data
is
important,
the
SD
card
should
be
replaced
at
least
once
a
year
to
prevent
the
possibility
that
a
previous
file
would
be
over
written
by
a
new
one
saved
at
the
exact
date
and
time
as
an
old
one
already
on
the
SD
card
from
a
previous
year.
(Note
regarding
SD
card
data
corruption:
Should
SD
card
data
corruption
inadvertently
occur
no
matter
what
the
cause,
sometimes
the
data
can
be
recovered
by
responding
affirmatively
to
the
operating
system’s
question
regarding
“Do
you
want
to…Scan
and
fix
files
on
the
SD
card”
when
the
SD
card
is
placed
into
a
PC/MAC.
This
often
“fixes
the
SD
card”,
but
it
is
not
always
successful.
Should
the
SD
card
be
unreadable
by
the
PC/MAC,
it
can
usually
be
reformatted
successfully
and
used
again,
but
this
permanently
removes
all
data
on
the
SD
card
and
this
reformatting
must
be
done
only
by
an
experienced
and
knowledgeable
computer
operator!
Anyone
doing
this
reformatting
of
the
SD
card
MUST
DO
IT
VERY
CARFULLY
AND
CARE
MUST
BE
TAKEN
TO
RE
‐
FORMAT
SPECIFICALLY
THE
SD
CARD
…AND
NOT
BY
MISTAKE
REFORMAT
ONE
OF
THE
COMPUTER’S
HARD
DRIVES
WHICH
WILL
DESTROY
ALL
DATA
ON
THE
PC
or
MAC
!!!
Unfortunately
this
user
mistake
sometimes
happens
and
it
is
catastrophic!
Be
careful.)
