sets
a
user-specied
xed

marker
.
The
stimulus and
response
values
of
the
reference
can
be
set
arbitrarily
,
and can
be
anywhere
in
the
display
area.
Unlike
markers
1
to
5, the
xed
marker
need
not
be
on
the
trace
.
The
xed
marker
is
indicated
by
a
small
triangle
1,
and
the
active
marker
stimulus
and
response
values
are
shown
relative
to
this
point. The
notation
\1REF=1"
is
displayed
at
the
top
right
corner of
the
graticule
.
Pressing
this
softkey
turns
on
the
xed
