*TST?
This query performs a complete self-test of the power supply. Returns ‘‘0’’ if
the self-test passes or ‘‘1’’ or any non-zero value if it fails. If the self-test fails,
an error message is also generated with additional information on why the test
failed.
*SAV { 1 | 2 | 3 }
This command stores the present state of the power supply to the specified
location in non-volatile memory. Three memory locations (numbered 1, 2 and
3) are available to store operating states of the power supply. The state storage
feature ‘‘remembers’’ the states or values of the following commands:
CURR, CURR:STEP, CURR:TRIG, CURR:PROT, CURR:PROT:STAT DISP,
OUTP, OUTP:REL, TRIG:DEL, TRIG:SOUR, VOLT, VOLT:STEP, VOLT:TRIG,
VOLT:PROT, VOLT:PROT:STAT, and VOLT:RANG
To recall a stored state, you must use the same memory location used
previously to store the state.
*RCL { 1 | 2 | 3 }
This command recalls a previously stored state. To recall a stored state, you
must use the same memory location used previously to store the state.
Note DISP {OFF|ON} can be stored and recalled in remote interface mode only.
Going to local mode automatically sets the display state to ON.
