Operators Manual
SOUR:PRES:LEV:IMM:VENT[?] [0|1] or
SOURCE:PRESSURE:LEVEL:IMMEDIATE:VENT[?] [0|1]
Read or set the vent status of the Controller. Read of the status will only indicate vented ('1')
once the Controller is vented and has zeroed once (if autozero is enabled).
Read Example:
Response:
1
Set Example:
SOUR:PRES:LEV:IMM:AMPL [?] [targ] [, rate] or
SOURCE:PRESSURE:LEVEL:IMMEDIATE:AMPLITUDE:[?] [targ] [, rate]
Read or set the set-point to control pressure to. If a new target is set, it will abort the current
process and control pressure to the set-point targ in the current measurement units and mode.
This happens only if targ is within acceptable limits of the currently active sensor. A targ value of
'0' will vent the 4322 when in gauge mode. Use the RDY and NRDY flags of the "RSR" register
using the
*RSR?
criteria. The optional rate argument attempts to reach the setpoint at the specified fixed rate
(unit/sec) and abort control once the setpoint is reached. If the optional rate argument is not given,
then normal control methods are used to reach and maintain the setpoint.

Response:
100
Set Example:
Set Example (fixed rate):
SOUR:PRES:MODE[?] [mode] or SOURCE:PRESSURE:MODE[?] [mode]
Read or set the Controller mode. Mode can be set to STATIC, STAT, DYNAMIC or DYN. This
only sets the mode and it does not start active control.
Read Example:
Response:
STATIC
Set Example:
SOUR:PRES:STAB[?] [stab] or SOURCE:PRESSURE:STABILITY[?] [stab]
Read or set the Controller control stability criteria that is required for a control set-point to be
"ready". stab is in percent of set-point.
Read Example:
Response:
0.500
Set Example:
SOUR:PRES:CONT[?] [hold] or SOURCE:PRESSURE:CONTROL[?] [hold]
Read or set the Controller control dead-band for control to achieve a steady state within. hold is
in percent of set-point.
Read Example:
Response:
0.200
Set Example:
STAT:OPER:COND? or STATUS:OPERATION:CONDITION
Read the operation register (see "488.2 Status System" on page 5-17).
Read Example:
Response:
0
STAT:OPER:ENAB[?] [flags] or STATUS:OPERATION:ENABLE[?] [flags]
Read or set the operation enable mask. Setting a specific bit(s) within the mask will cause the

query to determine when a new target has been reached and is within the ready
