If the electronic load’s current value is above the set overcurrent protection value, the electronic
load will automatically turn off and the VFD will display OCP. At the same time, the OC and PS bits
in the status register will be set and remain until they are reset.
Operations to Clear the OCP State
Check whether the input current is within the electronic load’s rated current or the programmed
protection current ranges. If it is outside the range, disconnect the device under test. Then press
any key on the front panel or remotely send SCPI command PROTection:CLEar. The OCP displayed
on the front panel will turn off and the load exits OCP protection state.
