What converts incoming signals to the correct output units?

[Dave@Quatro]

Hello and thank you in advance for your assistance.

I am brand new to Labview. I received the following email:  "...find the data array that is used to convert the incoming signals from the sensors into the correct units of measure for the given variable that is being recorded."

I hve been looking in the forums and tuorials and help sections, but honestly dont think I know enough at this point to even look in the right place.

Thank you again,

Dave

Hi Dave and welcome to the forums!

It sounds like the advice you were given is telling you to take the DAQmx Read data array and scale it to the correct units. For example, if you are reading from a pressure sensor in the range of 1 volt to 5 volts and this corresponds to 0 to 200psi, you would apply simple numeric scaling factors to your data array (subtract one and then multiply by 50). This way a user looking at your UI will visually be seeing psi rather than volts.

For more DAQ programming information, look at some of the links in my signature, especially the DAQ Getting Started guide!
