error -201204 channel does not support shunt calibration

[sfrosty]

I am getting an error when using the "Strain-Continuous Input" example VI which states cDAQ1Mod2/aio which is a 9237 does not support shunt cal when I initially click on the "Enable Shunt Cal" button. However all information I have found on the 9237 says it does support Shunt Cal!

Specifically: Error -201204 occurred at DAQmx Perform Shunt Calibration Ex (Bridge).vi:5560001

I have a 350 ohm 1/4 bridge configuration. I do get a bridge response. I get the same error regardless if I select Quarter Bridge I or II.

OK...

Hey sfrosty,

This error could be caused by a number of things including your device being far out of calibration, incorrect software configuration, or incorrect hardware configuration. I would recommend starting by ensuring that you have the correct bridge resistance and strain gage information as well as the proper wiring configuration. A guide on using the 9237 with strain gages and shunt resistors can be found here.

Are you "Super Dinosaur"?

Thanks for the reply! Starting with the first possibility, "device being far out of calibration", not sure which device you are referring to.

Kudos to Ryan Mayer, support

engr from NI whom came up with the solution:

In the Example "Strain - Continuous Input.vi":

"the case structure in the block diagram with the "Shunt Calibration and Wheatstone Parameters" label. In the True case, there is a DAQmx Perform Shunt Calibration VI. In your case, I'm assuming the dropdown menu directly underneath the VI says Bridge, but the 9237 requires it to be set to the Strain setting."

The Shunt Calibraion VI needed to have strain instead of bridge selected!
