Converting Engineering Unit to mV data

Solved!
Go to solution

Hello, I am trying to convert engineering units to mV. I have all the parameters needed but I am still learning and cannot figure out the formula. Once I can figure it out I can implement it into my labview.  The DAS system applies a gain so that also needs to be considered. Below is a snippet of data:

and here is the values I am provided by the test recording. I'm trying to get the mV with no gain from the engineering unit and have all the scale factors but I'm learning:

thank you so much for any help anyone is able to provide! I have been stuck on this .

Once I am able to implement a formula I can run it through my formula node on my program

So you have data in "EU". There is a scale in "EU/CNT" and another scale in "mV/CNT".

So the equation should be:

data [EU] / scale1 [EU/CNT] * scale2 [mV/CNT]
= data / scale1 * scale2 [EU / EU/CNT * mV/CNT]
= data / scale1 * scale2 [mV]

 Don't you have a manual for your "DAS system"?

Have you tried something?

You need to know the formula or you need to understand how to implement the formula in LabVIEW Environment?

Simple Arithmetic operation will help if you have a formula and if you are not aware of constructing the formula to use in formula node.

Thank you GerdW! 

do you know with gain displayed if my data is after gain when its in EU unit? or would i need to apply gain after converting it with formula? I guess i should check the manual if that is a question that differs per system.

you are right I am a goof I said "data acquisition system system" haha

thanks again

Yes!

(In general it is a good idea to read the manual…)
