OCP Delay
The power supply may momentarily has a peak current value beyond the OCP value when it is turned on, when an output value is programmed, or when the output load is connected. In most cases, these temporary conditions would not be considered an over-current protection fault, and you do not need to disable the output. The series power supply ignores this status bit during the specified delay period (10 ms by default). Once the OCP delay time has expired and if the current is still beyond the limit, the output will shut down. You can also set the OCP delay period by sending :OUTPut:OCP:DELAy [CH1|CH2| CH3], {|MINimum|MAXimum} SCPI command (refer to the series Programming Guide). The delay can be programmed from 0 to 1000 ms.
