We are getting ready to do some strain gauge testing and wanted to iron out some questions ahead of time, for the purpose of following best practice. We will be using NI-9237, NI-9944, Cdaq controller, 120 ohm, 3 grid rosette's. My questions are as follows and any input is much appreciated.
1.) Is it preferred to use NI-9237 to acquire strain or voltage?
2.) If acquiring strain, what is the best method to determine initial voltage?
3.) Is there a process or specification for qualifying strain gauge measurements?
