Re: SCXI-1112 Calibration Constants - Same for NI-DAQ and NI-DAQmx?

Hello RickyB, 
The Calibrate SCXI VIs and functions for DAQmx are designed to make calibration of the SCXI-1112 an easy process.&nbsp; For the most part, they perform the same steps as the Traditional DAQ functions.&nbsp; The <a href="http://zone.ni.com/devzone/cda/tut/p/id/4845" target="_blank">tutorial</a>&nbsp;you mentioned is a great method for calibrating each of the channels of the SCXI-1112 individually using an external reference.&nbsp; Also, with the SCXI-1112 and DAQmx you have the option to self-calibrate the device.&nbsp; This self-calibration mechanism uses the onboard 5V reference for the SCXI-1112 to calibrate each channel.&nbsp; As a result, the Traditional DAQ and DAQmx calibration procedures can perform the same operations up to this point.&nbsp; The VI Setup SCXI Calibration 1102.vi requires you to pick a channel to calibrate.&nbsp; This function causes the output of this channel to be output on the rear connector of the SCXI module.&nbsp; This is how the signal would be rerouted to the terminals on the connector block in figure 1 of the above tutorial.&nbsp; &nbsp;The 5V reference also has an option to be calibrated to compensate for offset drift and temperature variations on this reference.&nbsp; This reference is highly stable and does not require calibration very often.&nbsp; However, if you would like to calibrate this reference you will need to use the Traditional DAQ functions.&nbsp; The external calibration data for the SCXI-1112 is the same whether you externally calibrate in DAQmx or Traditional DAQ so you can calibrate in Traditional DAQ and use the module in DAQmx without issue.&nbsp; This was reported to R&amp;D (#123272) for further investigation.&nbsp; Post back if you have any questions.&nbsp;
