12 INDIRECT ACTION KEYS
This section
refers to the action keys, which are pressed repeatedly to
step
through
a list of selections
until the one
required is
displayed.
12.1 SWEEP
> >
Remote command
is SW/. Refer to Chapter
4,
Section 6. 13.
Applies the sweep polarisation
to the ceil (as set up via the SWEEP menu). A
voltage or current sweep
is
initiated, if
the SI 1287 is in P STAT or G STAT
mode,
respectively. Selecting {sweep ramp} or {sweep
step}
initiates
an analog
ramp or a digitally stepped sweep, respectively.
When the SWEEP action key is pressed,
its
LED
flashes on and off during a
sweep initialisation period (possibly several
seconds), and continues to flash
during the
user-selected delay (if any). It glows steadily, only
when
the sweep
itself starts, switching off at the end. For
stepped sweeps the initialisation period
may
be too
short
to cause the LED to flash.
Selecting {sweep off} will cause the sweep
to halt. The polarisation will be held
at the current level
if OFF MODE is set to freeze. Otherwise the cell will
be
disconnected.
CAUTION:
During
the sweep initialisation period
the existing
value
of
POL V
(or POL I) applied briefly
to the cell before the
sweep
generator has settled to the
proper starting value.
To avoid risk of damage to sensitive cells,
set ON MODE,
in
the
I MEASURE
menu, to rest
V/I.
12.2 PLOT
> >
Remote command
is PL/. Refer to Chapter
4,
Section 6.21.
Allows the selection
of a
plotting action
(as set up via the PLOT menu).
{graph}
Causes measurements to be plotted, if available. Only the graph
itself is drawn
by means of this
selection; plot
borders, axes,
title, grid and annotations are not output.
{axes} Draws the plot
borders, division marks (or grid if GRID is
’on’), annotations
(if TEXT is ’on’), title (if TITLE and TEXT
are ’on’) and axes. If the origin is set
to
coincide with
a
comer
of the plotting field, the
axes are not separately visible in the
plot.
{min.}
&
{min.} These selections move the plotter
pen
(in
the ’up’
position)
to the lower left-hand
comer, or to the upper right-hand comer
respectively,
of the plotting field set up via the PLOT {SIZE}
menu. These two selections can
be used to
check the size
and
position of the plotting field
before a plot is run.
{zero} ’Parks’
the
plotter
pen currently in use in its home position.
{off} Stops the plotting
of
the
graph (not the axes), and ’parks’ the
pen.
