*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.
