Software

Calibrating the NI 9263 requires the installation of NI-DAQmx 9.6 or later on the calibration 
system. You can download NI-DAQmx from 

ni.com/downloads

 NI-DAQmx supports 

LabVIEW, LabWindows

/CVI

, ANSI C, and .NET. When you install NI-DAQmx, you only 

need to install support for the application software that you intend to use.
