Low Priority Alarm

A low priority alarm indicates that an equipment fault has occurred and the device is unable to
provide a measurement value. See table 8 for parameters, fault messages, and possible cause.
Low priority alarms are both audible and visual:
• Audible alarms beep slower in a low priority situation than in a high priority situation.
• The fault message displays on the monitor.
