FP-AI-100 Cross Communication

Has anyone had issues with cross communication by wiring up more than one channel?  Simply hooking up additional instrumentation effects the voltage.  There are no naked wires touching each other and I’ve double checked the wiring to be sure that the wires are not cross connected from one channel to another.  Maybe this is a result of the wires not being shielded?

Hi nonenanone,

You could be seeing cross communication because of unshielded wires. Depending on yoru setup, you might also want to check this document on Field Wiring and Noise. Can you post a picture of your setup? Where are you seeing the difference in voltage?
