UIA-0402N and UIA-0800N Issues

Recommended Posts

So we have several of the unistream units out there. But recently the last 2 we built with the exact program on them. Are having issues with analog inputs. They started to jump all over the place. Tried different signal wires same reading. Multi meter run series and analog signal not jumping all over the place, just smooth reading. I don't know if it the modules or the last firmware update.  Was wondering if you guys had any thoughts.

Thanks

Rog

Have you run your meter over all the power and earth lines?  Modules are commoned to the supplies providing the sensors?

cheers, Aus
