Software Requirements
Calibrating the FD-11605 requires the installation of NI-DAQmx on the calibration system. NI
recommends using the latest NI-DAQmx driver. Earliest driver support version for calibrating
the FD-11605 is listed in the following table.
Driver
NI-DAQmx
You can download NI-DAQmx from ni.com/downloads. NI-DAQmx supports many
programming languages, including LabVIEW, LabWindows
Basic .NET. When you install NI-DAQmx, you only need to install support for the application
software that you intend to use.
