Non-linear signals

[Omar-Abdelhameed]

Hello gentlemen, I have question regarding reading output voltage (0-10) from my sensors using NI cDAQ9174, and I am using straight line equation (y= mx + b) so the user needs to enter the voltage at minimum range of the sensor and voltage at maximum range of the sensor and then the code will make the calculations to convert the read voltage signal to the phenomena (unit). What if the sensor signal out is not linear, is there any method to do so I can do for that. Thank you.

The simplest Custom Scale you can create is (of course) a Linear Scale.  However, DAQmx allows you to create polynomial or table-driven scales, as well.  Try doing a Web search for DAQmx Custom Scales -- you can find links to LabVIEW Help sites.  You can also use the LabVIEW Help system (search for Custom Scales).
