Returned Parameters <NR2>
Related Commands CURR:PROT:STAT VOLT:RANG MODE
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.
Command Syntax [SOURce:]CURRent:PROTection:STATe<bool>
Parameters 0|1|OFF|ON
*RST Value ON
Examples CURR:PROT:STAT 0 CURR:PROT:STAT OFF
Query Syntax [SOURce:]CURRent:PROTection:STATe?
Returned Parameters 0 | 1
Related Commands OUTP:PROT:DEL
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.
