Convert Scaling Using Traditional NI-DAQ (Legacy) in LabVIEW
If you need scaling, you can either use an analog input voltage virtual
channel with a custom scale configured in MAX or SCXI channel strings,
and provide scaling in your LabVIEW application.
channel with a custom scale configured in MAX or SCXI channel strings,
and provide scaling in your LabVIEW application.
If you are using SCXI channel strings, you can easily convert the
SCXI-1125 voltage signal measurements in your application into scaled
units of interest such as pounds or newtons. LabVIEW has some common
conversion scaling functions such as the Scaling Constant Tuner VI in the
function subpalette Data Acquisition»Signal Conditioning.

You also can use an Expression Node or Formula Node to convert voltage
signal measurements into whatever units your application requires. You can
find an Expression Node in the function subpalette Numeric. You can find
Formula Nodes in the Function subpalettes Analyze»Mathematics»

Analyze and Display Using Traditional NI-DAQ (Legacy) in LabVIEW
In LabVIEW, you can easily analyze SCXI-1125 measurements with a
variety of powerful analysis functions that you can find in the function
subpalettes Analyze»Waveform Conditioning and Analyze»Signal
Processing. You can perform post acquisition processing such as
waveform comparisons, harmonic analysis, and digital filtering. For more
information about these VIs, refer to the LabVIEW Analysis Concepts
manual. You also can use the LabVIEW Help for more detailed information
about how to use the analysis VIs.

In LabVIEW, you also can easily display SCXI-1125 measurements with a
variety of graphical waveform graphs, numeric slides, gauges, and other
indicators. You can find useful graphical controls and indicators for user
interaction with your application in the controls subpalettes. For more
