Software

Calibrating the NI 9209 requires the installation of NI-DAQmx 15.1 or later on the calibration
system. You can download NI-DAQmx from

ni.com/downloads

. NI-DAQmx supports

LabVIEW, LabWindows

™

/CVI

™

, C/C++, C#, and Visual Basic .NET. When you install

NI-DAQmx you only need to install support for the application software that you intend to use.
