VOLT SUBSYSTEM
This subsystem programs the output voltage of the power supply.
VOLT
This command directly programs the immediate voltage level of the power supply. The immediate level is
the voltage applied at the output terminals.

VOLT 1 0.500; VOLT:LEV 1 30.0
VOLTage[:LEVel]? <NR1>
VOLTage[:LEVel]? <NR1> MAX
VOLTage[:LEVel]? <NR1> MIN
<NRf>: VOLT? returns the present programmed volatge level.
VOLT? MAX and VOLT? MIN return the maximum and minimum
programmable voltage levels.
*SAV *RST
VOLT:PROT
This command sets the over-voltage protection (OVP) level of the power supply. If the output voltage
exceeds the OVP level, and the VOLT:PROT:STAT is set to ON, then the power supply output is
disabled and the Questionable status register (STAT:QUES?) OV bit is set . An over-voltage condition can
be cleared with the OUTP:PROT:CLE or VOLT:PROT:CLE or *RST command after the condition
that caused the OVP trip is removed.

VOLT:PROT:CLE
This command clears the over-voltage protection status, and it dose not clear the over-voltage protection
setting (VOLT:PROT:STAT). After this command, output remains in OFF state.
