10.8 Setting up National Instrument Multifunction Data Acquisition devices (NI-DAQ) to capture energy data

In addition to the Energy Probe, you can also use NI-DAQ devices to gather energy data from your target and view the results in Streamline.

To collect power statistics using a NI-DAQ device, you must have the following:
To set up your NI-DAQ device, follow these steps:


  1. Connect the Ai1 connections on the NI-DAQ device to go across the shunt resistor on your target.
  2. Connect Ai0 negative to ground.
  3. Also connect Ai GND to ground.
  4. Loop Ai0 positive to Ai1 negative.
    The Ai0 connectors are measured across the load, which is used to derive the voltage.

  5. Repeat steps 1 through 3 using the other connectors on the NI-DAQ device to measure additional channels.
  6. In the Streamline Data view, click Capture & Analysis Options.
  7. Select the NI-DAQ option from the Energy Capture drop-down menu.
  8. Enter a valid system name in the Device field.
    To get the system name of your National Instruments device, you must run the NI-DAQmx Base List Devices application, installed as part of the NI-DAQmx software package.
  9. Click the Select the energy capture tool button in the Tool Path field.
  10. Locate caiman in your DS-5 installation directory and select it.
  11. Click Open.
