SI1287 REMOTE COMMANDS
This section lists the instruments remote
commands.
The
commands are the same
for both RS423
and GPIB operation. The majority of codes are qualified by
a
numeric arguement. In the following list:
I is an integer of
up to 3
digits.
/,/
is
two integers of up to 2 digits each, separated by a comma.
F is a floating point number +n.nnnnE±xx.
S
is
a string of up to 20 ASCII characters.
Note that the underlined commands relate
to
the
default settings.

Command
Function
POO
Sets
SI 1287
to
operate
as a polentiostat.
POl Sets SI 1287 to operate as a galvanostat.
PVF Defines the d.c. potential, in volts, that is
to he
applied across RE1
and RE2
for
the polentiostat.
(F=-14.5 to +14.5)
PCF Defines the direct current, in amps, that
is to
flow through the cell
for the galvanostat.
(F=-2 to
+2)
PIO
An
external signal (typically from an
FRA) is added to the
polarization selected by PVF or PC F,
at a
gain
of
xl.
PI1
An external
signal
(typically from
an
FRA) is
added
to the
polarization selected by
PVF
or PC F, at a gain of xO.Ol (-40dB)
PW1
Selects polarization ON. (assumes ON mode.)
PWO Selects polarization OFF.
(assumes standby mode.)

6.3 POLARIZATION ON MODE
Command On Mode
ONO Prepares the instrument for the Pol V/I
mode.
When
polarization
ON is
selected
the cell is
polarized at its
previously
defined level.
By delimit, this is zero volts for the potentiostat and zero current
for the galvanostat; otherwise, it is the level defined
by the last
PVF or PCF command
(see Table
6.1).
ONI
Prepares the instrument for the Rest V/I
mode.
When
polarization
ON
is
selected
the cell is
held at its rest potential (potentiostat) or at
zero current (galvanostat). Changing to ONO will then cause the
polarization voltage/current to take
up
the value
defined by
PVF or
PCF
