Environment

Hardware

  • NI-9237
  • NI-9236

Driver

  • NI-DAQmx

Is there a way through software to close and open the shunt cal switch? I want to close the shunt cal switch, then I read the value, then open the switch all by software. Can I do that?

Yes, you can use "Analog Input:General Properties:Signal Conditioning:Bridge:Shunt Cal:Shunt Cal Enable" property to do this.
  1. On your Block Diagram drop DAQmx Channel Node
  2. Then navigate to Shunt Cal Enable property: AnalogInput>>General Properties>>Signal Conditioning>>Bridge>>Shunt Cal>>Shunt Cal Enable
  3. Finally, change the property to be writable. Right click this property and change it to "Change All To Write"

Additional Information

You can explore the properties supported by a device if you have the device driver installed.
  1. Open LabVIEW Help (Help>>LabVIEW Help...) and search your device.
  2. Look for the device supported properties.
