Configure the PXIe-4144 for Measuring

Once you configure channels and they are in the Running state, the PXIe-4144 can take measurements.

Use the niDCPower Measure property or the NIDCPOWER_ATTR_MEASURE_WHEN attribute to configure how NI-DCPower takes measurements.

The following table lists the settings for the niDCPower Measure property or the NIDCPOWER_ATTR_MEASURE_WHEN attribute.

Measure When Details
On Demand Acquire measurements on demand using the niDCPower Measure VI and the niDCPower_Measure function to measure either the voltage or the current on a single channel. Or use the niDCPower Measure Multiple VI and the niDCPower_MeasureMultiple function to measure both the voltage and the current on multiple channels. When you call these VIs and functions, the PXIe-4144 takes a measurement and returns it.
Automatically after Source Complete The PXIe-4144 acquires a measurement after every source operation and stores it in a buffer on the device. You can use the niDCPower Fetch Multiple VI and the niDCPower_FetchMultiple function to retrieve measurements from the buffer.
On Measure Trigger The PXIe-4144 acquires a measurement when it receives a Measure trigger and stores it in a buffer on the device. You can use the niDCPower Fetch Multiple VI and the niDCPower_FetchMultiple function to retrieve measurements from the buffer.
