10.2. Cumulative daily time above/below the
limit
The alarm trigger algorithm is based on a single event, although the Fridge-tag is measuring on a daily
basis the individual total time above or below the temperature limits. This measurement is not used for
any alarm condition. These recordings are only available in the generated PDF/ASCII files.
Note:
It could be that the total cumulative time above/below the temperature limits is longer than the
configured single-event alarm time without any alarm triggering.
Example setup: lower temperature limit <–0.5°C, duration >1 hour
In the above example multiple low temperature deviations with exposure times of less than 1 hour
occurred. The cumulative daily time below the limits adds up to about 3.5 hours but no alarm will be
triggered. The same behavior also applies to the upper alarm.
