Gentlemen,
We have some failure of DVC 6200 and with consultation of Emerson representative; we recognized that DCS signal has higher Noise voltage. It was resolved with their help, but we are unable to find out the way of finding Noise voltage with communicator 475.
With this method we could measure Noise level (voltage) whether is under acceptable range or not. My question is how we could find Noise voltage through 475 communicator, kindly provide step for finding online trouble solution.
