I am using NI 9237 to measurement the strain. But I recently found there is a huge noise in the data. It sometimes has the noise but sometimes doesn't. I attached one of the data I collected. There is no force applied on the item where I attached strain gauges. Can anyone help me to figure it out?
Well, we don't know anything about your hardware setup nor do we know about your lab environment...
Two generic suggestions for your generic question:
- Try to reduce noise before measurement, like using (better) shielding, improving grounding issue, and so on.
- Try to use filters on your measurement data...
You should prefer the first option!
