問題敘述
嘗試通過NI MAX自檢我的PXIe-4163 SMU時，出現以下錯誤：
The self test failed.
The Overcurrent Protection (OCP) has been activated. OCP is triggered when a fault condition occurs that would otherwise cause the device to sink or source current beyond its specifications for an excessive amount of time. OCP might be triggered, for example, if a voltage greater than the operating range of the device is connected at the output, or if a voltage is foreced on the output that exceeds the Voltage Limit value when using the niDCPower Configure Output Function set to DC Current.
Channel Names: 17

當前沒有任何連接到SMU輸入。為什麼會看到此OCP錯誤？
