For vibration measurements, alarms are automatically acknowledged when a new measurement reading below the limit is reported to AvaNet. The actual alarm indication (yellow marking) is removed only after a new measurement reading below the limit has been reported and 24 hours have passed since the alarm was generated.
It is possible to manually remove the alarm indication by acknowledging the alarm yourself, on condition that a new measurement reading below the limit has been reported in to AvaNet. This manual acknowledgement can be done by ticking/checking the Acknowledge column. You might have to add the column to make it visible.
