How do I calculate strain from a volt amplitude vs time plot that labview generates

[Jason K2011]

I have set up four strain gages, a DAQ system and a coded output in labview. After running my program labview gives me a voltage vs time plot. How do I convert the voltage measurements to strain? My strain gages are configured in a Wheastone quarter bridge configuration. Thanks in advance for the help!!!!

Hi Jason,

You need to do the scaling.

Hello Jason,

On your task in Measurement and Automation Explorer you can either set up a scale or create a task for force measurements. When you acquire this it should give you the strain value and then you can change the label on the Y Axis to customize it.

Think you Miriam for the insight.
