Taking single value from Floating Point Scalar Wire

Solved!
Go to solution
Highlighted

Hi all,

 

I just started working with LabVIEW, and I am trying to create a zero-ing (tare) function for a pressure transducer. To do this, I would like to have a switch that takes the current value of a floating-point scalar wire (orange), stores it, and subtract it from the wire. Is there any way to do this? I am using LabVIEW 2014.

 

Thank you

Why would it need to store it in order to subtract it, the wire is the data!

 

Or do you want to subtract the current value from the previous value of the same wire? In this case, use a feedback node.

 

(Typically, it would make things much clearer if you could attach a simplified version of the VI)
