Issue Details

I have been using National Instruments' built in logging functions to store DAQmx data in TDMS. Now, I want to save the unscaled values, but haven't found a way to do this.

Solution

The build in TDMS logging functions are configured to log scaled data. In order to log unscaled data, you will need to use the lower level TDMS functions and set it up manually. For more information on how to do this, please reference this tutorial

Additional Information

You can read DAQmx unscaled data in LabVIEW by using a DAQmx Read VI.

In Measurement Studio, you can read unscaled values by using an analogUnscaledReader.
