In a dual
trace
format,
two
DISPLAY SETUPs
are
shown, and the Field
Selector
can be
moved
between the two, and
pressing
SETUP LABEL
"Display"
once
moves
the Field
Selector
to
the
label field
of
whichever
DISPLAY SETUP in
which
it
was
previously
placed. Pressing the
pushkey
further
toggles
the Field
Selector
between the
two
DIS-
PLAY SETUP label fields.
Similar
principles
apply
to
the CURSOR push key,
for
exam-
ple:

When the
required
parameter
has been accessed using the FIELD SELECT
controls,
its
value can be entered using any
of
three
different
methods:

These
two
pushkeys are used
to
increment
or
decrement
the chosen
parameter
with
the smallest allowable step. When
they
are
held
down
continuously, the
parameter
is
incremented
or
decremented
repeatedly. The
parameter
value
cannot
be
moved
out-
side
its
allowed range,
nor
can an illegal
parameter
setting,
(that
is one
which
has no
meaning
for
the selected MEASUREMENT, DISPLAY,
or
CURSOR SETUP), be selected.

Continuous
Parameter
Entry
Turning the
knob
to
the
right
with
respect
to
its
rest
position
continuously
increments
the
parameter
value. Turning
it
to
the
left
continuously
decrements
the
parameter
val-
ue. The
rate
of
increment
or
decrement
is
proportional
to
the angle
of
turn
of
the
knob
and the
adjustment
range
of
the selected
parameter.
The
parameter
value
cannot
be
moved
outside
its allowed range,
nor
can an illegal
parameter
setting
be selected.
