Current Subsystem
This subsystem programs the output current of the power supply.
CURR[:LEV]
Sets the immediate current level or the pending triggered current level of the power supply. The immediate level is the
current programmed for the output terminals. The pending triggered current level is a stored value that will be transferred to
the output when a trigger occurs. If no pending triggered level has been programmed, then the immediate command
programs both levels to the same value. Once a trigger level is programmed, it is unaffected by subsequent changes to the
immediate level.

Returned Parameters <NR3> CURR?
and
CURR:TRIG?
return presently programmed current levels. If the
TRIG
level is
not programmed, both returned values are the same.
CURR? MAX
and
CURR? MIN
return the maximum and minimum programmable immediate current levels.
CURR:TRIG? MAX
and
CURR:TRIG?
MIN return the maximum and minimum programmable triggered current levels.
CURR:PROT:STAT
Enables or disables the power supply overcurrent protection function (OCP). If the OCP function is enabled and the output
current exceeds the programmed immediate level then:
♦
the power supply output is disabled
♦
the Questionable Condition status register OC bit is set (see "Status Reporting").
An overcurrent condition can be cleared with the
OUTP:PROT:CLE
command after the condition that caused the OCP trip
is removed.
