    keyword=Noisy pressure sensor probably causes the alarm

    After checking and monitoring for a while, it seesm everything behaves normally, except one of the pressure transducers having large noise/fluctuations. We may need to change to a different pressure sensor for the low pressure alarm. At the meantime (before the change), target operator should check to make sure temperature fluctuation and pressure fluctuation from other sensors are all within normal range, which are in the EPICS alarms.
