Calling niDCPower_ResetDevice in a session created with Initialize with Independent Channels will repeat the device reset for each channel in the sessionIn sessions created using the niDCPower_InitializeWithIndependentChannels function or niDCPower Initialize with Independent Channels VI, calling niDCPower_ResetDevice or niDCPower Reset Device VI will incorrectly call it once for every channel instead of once per instrument used in the session. As this is a relatively slow operation, the increased time can be considerable.
Workaround: Close the session, call System Configuration Reset Device on each instrument you wish to reset, then reopen the session. Alternatively, close the session, open a new session to one channel of each instrument, call niDCPower_ResetDevice, close the session, and reopen a session to the same set of resources used in the first session.

The NI PXIe-4162 and PXIe-4163 are unable to source up to 25.2 VThe absolute maximum voltage allowed on the output pins for the PXIe-4162 and PXIe-4163 is +-25 V. When using Overranging Enabled, NI-DCPower allows specifying a maximum sourcing voltage of 105% of the range, or 25.2 V. This exceeds the absolute maximum voltage specification. Beginning with NI-DCPower 2024 Q3, the maximum voltage for sourcing when Overranging Enabled is true has been reduced to 102.5% of the range, or 24.6 V. The maximum measurement voltage has also been reduced to 102.5% of the range, or 24.6 V. Workaround: Do not attempt to set the voltage beyond 24.6 V.

Small memory leak when calling niDCPower Reset Device on the NI PXIe-4135/6/7On the PXIe-4135, PXIe-4136, and PXIe-4137, there is a small memory leak whenever niDCPower_ResetDevice is called.
Workaround: There is currently no known workaround for this issue. |

NI-DCPower Fetch and Measure may cause a system crash under very high CPU load when using the PXIe-4147, PXIe-4162, or PXIe-4163When retrieving measurements from the PXIe-4147, PXIe-4162, or PXIe-4163, a race condition may cause a system crash (Blue Screen of Death). The likelihood of the crash increases with an increased number of simultaneous calls to niDCPower Fetch Multiple or niDCPower Measure Multiple (for example, when using a Parallel For Loop in LabVIEW). Workaround: Serialize calls to niDCPower Fetch Multiple and niDCPower Measure Multiple. Use niDCPower Wait for Event to wait for the Measure Complete Event prior to calling Fetch Multiple.

NI-DCPower: The 1 uA and 10 uA current ranges on the PXIe-4162 and PXIe-4163 10pA variants may be out of specification.The 1 uA and 10 uA current ranges on the PXIe-4162 10 pA and PXIe-4163 10pA variants may be out of specification. The current offset measurement error in the 1 uA and 10 uA ranges exceed the published specifications when the board temperature deviates by a few degrees from the external calibration temperature. Self-calibration will not rectify this error. As the board temperature diverges from the external calibration temperature, the probability of measurement error falling outside of specifications increases. Note: The PXIe-4162 100 pA and PXIe-4163 100 pA variants are affected.
Workaround: Perform external calibration using NI-DCPower 2024 Q3 Patch 3 or newer. Ensure you only use the instrument in a system with NI-DCPower 2024 Q3 Patch 3 or newer.
