Note  Constant voltage mode is synonymous with voltage-controlled mode.

To determine when an output channel is operating in constant voltage mode, use the status indicators on the front panel of the NI PXI-4110/4130/4132 or NI PXIe-4112/4113/4154, the niDCPower Query Output State VI, or the niDCPower_QueryOutputState function.
