They're probably recorded automatically but logs are still taken as way to ensure human eyes are on the indicators, like security guards have to scan a waystation point to prove they were there. I haven't been in a plant for over three decades so I don't know either. One thing I carried with me through life was to "always trust your indicators." It's too easy to look at an anomaly and conclude the gauge is broken.
