Two signals instead of one

Hello everybody,

 

While running a newly aquired torque load cell [connected to SG unit inside of SC-2345, and wired to a PXI-6221 board], I faced some strange phenomenon. Instead of one signal I can observe two, one of them is a torque signal, but another one is of different nature. This second signal can fluctuate when I manipulate with the connection cord (J24) from PXI 6221M to SC-2345, and also when I create a torque(it almost follow the torque signal). I am attaching the test VI that I was using. I would appreciate greatly any help with resolving this issue and removing the second signal.

I would suggest checking your hardware connections. See this document, it talks about unexpected voltages on analog input channels, possible reasons and how to troubleshoot them.  🙂
