Issue Details

I need to use a different custom scale for different inputs from my CompactDAQ. How do I implement that in LabVIEW?

Solution

You can specify and combine channel settings in CompactDAQ data acquisition. The following steps outlines how to create a single DAQmx Task with two analog inputs that require separate custom scales:

  1. Using the DAQmx Create Virtual Channel choose the channel and the custom scale. Repeat this for each custom scale and input pair
    •  Additionally, you can set other properties such as voltage limits.
  2.  Connect the output Task Out of the DAQmx Create Virtual Channel to the next DAQmx Create Virtual Channel input Task In.
  3. Repeat this process for all of the scale and input pairs.

Additional Information

You can Make a Custom Scale in Measurement & Automation Explorer.
