A.9 *OPT? — OPERATION COMPLETE QUERY
*OPT?
Syntax: *OPT?
Return value: option string which is a comma separated list
250 LST,.01 TMIN,655.36 TMAX,3 RL,40 MEM,4 DSM,CCAL
where:
xxx LST indicates maximum number of points supported by list
yyy TMIN indicates minimum list dwell time in seconds
zzzzzz TMAX indicates maximum list dwell time in seconds
3 RL indicates keyboard lockout supported
aa MEM indicates number (aa) of save and recall memory locations
b DSM indicates number (b) of characters in front panel display
CCAL indicates calibration can be performed without manually adjusted pots.
Description: Lists configuration parameters in format compatible with LabView and C routines. Configuration
parameters include List settings (number of points, minimum dwell time, maximum dwell time),
whether keyboard lockout is supported, number of save and recall locations, and whether calibration
is performed without mechanical pots. For example 250 LST,.01 TMIN,655.36 TMAX,3 RL,40 MEM,4
DSM,CCAL means the unit supports up to 250 points in a list, minimum list dwell time is 0.01 seconds,
maximum list dwell time is 655.36 seconds, keyboard lockout is supported, 40 memory locations avail-
able for Save and Recall, the front panel has a four-character display, and calibration does not require
manually adjusted pots.
A.10 *RCL — RECALL COMMAND
*RCL
Syntax: *RCL<integer> (1 to 40)
Description: Restores power supply to previously defined levels of output voltage, output current, overvolt-
age protection, overcurrent protection, output state (on or off) and relay state. Executing *RCL
recalls the settings previously saved by *SAV from one of 40 memory locations, changing the voltage,
current, overvoltage protection, overcurrent protection, and output on/off state accordingly. If RELAY
mode was set to MANUAL when *SAV was executed, relay state is also restored; relay state is not
saved upon power off. The following parameters are affected by *RCL: VOLT, CURR, VOLT:PROT,
CURR:PROT, and OUTP.
A.11 *RST — RESET COMMAND
*RST
Syntax: *RST
Description: Resets power supply to the power on default state. The power supply is programmed to the power
on values of the following parameters: CURR[:LEV][:IMM] = MIN (minimum), VOLT[:LEV][:IMM] = 0,
OUTP[:STAT] = 0 (OFF). In addition, *RST sets INIT:CONT to OFF, sets VOLT:MODE to FIXED, stops
all LIST or TRAN operations. (See example, Figure A-1.)
A.12 *SAV — SAVE COMMAND
*SAV
Syntax: *SAV<integer> (1 to 40)
Description: Saves the present state of output voltage, output current, overvoltage protection, overcurrent
protection, and output state on/off and (if RELAY mode is set to MANUAL) relay state to the
specified memory location. This command stores the present state of the power supply to one of 40
memory locations in non-volatile Memory. If RELAY mode is set to MANUAL from the front panel UTIL
menu, relay state, on or off, is also saved. The following parameters are stored by *SAV: VOLT,
CURR, OUTP, and VOLT:PROT, CURR:PROT. The stored values can be restored by the *RCL com-
mand.NOTE: If a Virtual Model setting is changed, previously stored settings may be outside the
range established by the new virtual model. In this case, when *RCL is executed, the value is cleared
to the default minimum (0V, minimum A) and an “out of range” error message is generated.
