CURRent:PROTection:STATe
This command selects overcurrent (OC) protection mode. If the overcurrent protection
function is enabled and the load current exceeds the programmed level, then the output is
disabled after a time delay specified by the CURRent:PROTection:DELay and the
Questionable Condition status register OC bit is set (see chapter 7). An overcurrent
condition is cleared after the cause of the condition is removed.
If the (OC) protection mode is disabled, the source operates in the Constant Current mode
and the output voltage will be reduced after a time delay specified by the
CURRent:PROTection:DELay and the Questionable Condition status register OC bit is set.
(see chapter 7). An overcurrent condition is cleared after the cause of the condition is
removed.

CURRent:PROTection:DELay
This command sets the delay time between over current limit condition and the response to
this condition. At the end of the delay, if the over current condition still exists, the response
will depend on the protection state.
If the protection state is on, the output voltage will fault to zero voltage. If the protection
state is off, the output voltage will reduced to a value that maintains a constant current
defined by the setting of the current limit.
Use CURRent:PROT:DEL to prevent momentary current limit conditions caused by
programmed output changes or load changes from tripping the overcurrent protection.
