- b) No limit when the Restart-up function is enabled.
Note: Restart-up will generate new data records and delete the previous stored data.
a. Alarm Settings:
- a Thresholds: Alarms when the data is out of limit.
- b) Types: Single/Cumulative.
- c) Delay: Used to compare with the alarm duration to judge if it is in alarm status.
- d) Alarm Settings and Results:
- Single Alarm: When the single temperature (humidity) is up to or exceeds the threshold duration, ≥ the delay time of alarm.
- Cumulative Alarm: When the cumulative temperature (humidity) is up to or exceeds the threshold time, ≥ the delay time of alarm.
- Alarm Duration: When the recorded temperature (humidity) is up to or exceeds the total threshold duration.
- Alarm Times: When the recorded temperature (humidity is up to or exceeds the threshold until to recover or end the record, considered as one alarm time.
