How to Read the Internal Autozero Channel of an NI 9211 in CompactDAQ

Hardware: CompactRIO>>Analog Input Modules>>NI 9211

Problem:
I would like to check what the internal autozero channel is reading on my NI 9211 in CompactDAQ.  How can I accomplish this? 

Solution:
This can be accomplished in both Measurement & Automation Explorer (MAX) and LabVIEW.

1. In MAX, open a test panel and select the _aignd_vs_aignd channel within the analog input tab.
   
   
   
   
    
2. In LabVIEW, select _aignd_vs_aignd for the DAQmx Create Virtual Channel physical channels input within your data acquistion task.
   
   
   

Note: To enable internal channels (such as autozero) to be selectable from the I/O constant drop-down, see the linked KnowledgeBase regarding I/O Name Filtering.
