*PSC causes a write cycle to nonvolatile memory. If *PSC is programmed to 0, then the *ESE and
*SRE commands also cause a write cycle to nonvolatile memory. The nonvolatile memory has a finite
number of write cycles (see "Table 1-2, Supplementary Characteristics"). Programs that
repeatedly write to nonvolatile memory can eventually exceed the maximum number of write cycles
and may cause the memory to fail.
Meaning and Type
Recall Device State
Recalling a previously stored st ate may place hazardous voltage at the power supply output.
Description
This command restores the power supply to a state that was previously stored in memory with a *SAV command to the
specified location. The following states are recalled:
CURR[:LEV][:IMM] OUTP[:STAT] OUTP:REL:POL
CURR:PROT:STAT OUTP :PROT:DEL VOLT[:LEV][:IMM]
DIG:DATA[:VAL] OUTP:REL[:STAT] VOLT:PROT[:LEV]
Sending *RCL also does the following:
• Forces an ABORt command before resetting any parameters (this cancels any uncompleted trigger actions).
• Disables the calibration function by setting CAL:STATe to OFF.
• Sets display functions as follows:
• DISP[:WIND][:STATe] to ON.
• DISP[:WIND]:MODE to NORMal.
• DISP[:WIND]:TEXT to ' '.
• Sets INIT:CONT to OFF.
• Sets TRIG:SOUR to BUS.
At power turn-on, the power supply normally is returned to the factory defined turn-on state (see *RST). However, it also
may turn on to the state stored in location 0 (see Turn-On Condition under "Chapter 5 - Front Panel Operation" of the power
supply Operating Guide).
