Software
Calibrating NI 6738/6739 devices and modules requires the installation of NI-DAQmx on the
calibration system. You must use NI-DAQmx 17.6 or later. Refer to the
NI-DAQmx Readme to
ensure support for the device you want to calibrate. You can download NI-DAQmx from
ni.com/downloads
. NI-DAQmx supports many programming languages, including
LabVIEW, LabWindows
™
/CVI
™
, C/C++, C#, and Visual Basic .NET. When you install
NI-DAQmx, you need to only install support for the application software that you intend to use.
