Issue Details

I need to manually control the shunt calibration relay on my NI strain/bridge module in DAQmx without actually performing a shunt calibration.

Solution

This can be done using the Shunt Cal Select and Shunt Cal Enable properties. In LabVIEW, this can be set with a DAQmx Channel Property Node:
 

Here is the menu path to find these properties:
AI»General Properties»Signal Conditioning»Bridge»Shunt Cal»Shunt Cal Select
AI»General Properties»Signal Conditioning»Bridge»Shunt Cal»Shunt Cal Enable


Shunt Cal Select is used to select the desired relay, and Shunt Cal Enable will open or close it.
