Rosemount lower trim and zero trim
I have a question regarding the Rosemount 3051 differential pressure meter. When performing a lower trim using the communicator, should I simply close the low-pressure valve and open the equalizer to trim with equalized pressure? Or, should I vent it to the atmosphere and trim it at zero pressure? Additionally, when should I perform a zero trim versus a lower trim?
