A.9 *RCL — RECALL COMMAND
*RCL
Syntax: *RCL (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.10 *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] = 0, VOLT[:LEV][:IMM] = 0,
CURR:PROT[:LEV] = max overcurrent value (see Table 1-2, VOLT:PROT[:LEV] = (maximum over-
voltage value (see Table 1-2), OUTP[:STAT] = ON. (See example, Figure A-1.)
A.11 *SAV — SAVE COMMAND
*SAV
Syntax: *SAV (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 (see PAR 3.2.11.3),
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 (see PAR 3.2.5) 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.
A.12 *SRE — SERVICE REQUEST ENABLE COMMAND
*SRE
Syntax: *SRE where = value from 0 - 255 per Table A-3, except bit 6 cannot be pro-
grammed.
Description: Sets the condition of the Service Request Enable register. The Service Request Enable regis-
ter determines which events of the Status Byte Register are summed into the MSS (Master
Status Summary) and RQS (Request for Service) bits. RQS is the service request bit that is
cleared by a serial poll, while MSS is not cleared when read. A "1" (1 = set = enable, 0 =
reset = disable) in any Service Request Enable register bit position enables the correspond-
ing Status Byte bit to set the RQS and MSS bits. All the enabled Service Request Enable
register bits then are logically ORed to cause Bit 6 of the Status Byte Register (MSS/RQS)
to be set. Related Commands: *SRE?, *STB?. (See example, Figure A-1.)
