Current Subsystem
This subsystem programs the output current of the power supply.
CURR
CURR:TRIG
These commands set 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 level is a stored current value that is
transferred to the output terminals when a trigger occurs. A pending triggered level is unaffected by subsequent CURR
commands and remains in effect until the trigger subsystem receives a trigger or an ABORt command is given. If there is
no pending CURR:TRIG level, then the query form returns the CURR level. In order for CURR:TRIG to be executed,
the trigger subsystem must be initiated (see INITiate).

Returned Parameters <NR3> CURR? and CURR:TRIG? return presently programmed immediate and
triggered levels. If not triggered level is 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
This command enables or disables the power supply overcurrent protection (OCP) function. If the overcurrent protection
function is enabled and the power supply goes into constant-current operation, then the output is disabled and the
Questionable Condition status register OC bit is set (see "Chapter 4 - Status Reporting"). An overcurrent condition can be
cleared with the OUTP:PROT:CLE command after the cause of the condition is removed.
Command Syntax [SOURce]:CURRent:PROTection:STATe <bool>
Parameters 0 | 1 | OFF | ON
*RST Value OFF
Examples CURR:PROT:STAT 0 CURRENT:PROTECTION:STATE OFF
