When the RH and hours are exceeded, the alarm will sound for 5 seconds and then every 30 minutes, regardless of the current %RH. The meter continues to monitor conditions, accumulating the total hours of continuous high humidity at the set point. If the moisture level falls below the set point, the accumulation of hours stops until the %RH again exceeds the set point.

For example: Assume you have selected 60%RH and 12 hours for your set points. The alarm is activated after humidity exceeds 60% for 12 continuous hours. The continuous hours are tracked and displayed until the humidity falls below the alarm level (60%RH). If the RH falls below 60%, the hour count stops. If the humidity exceeds the set point again for a period of 12 continuous house, the total hours of continuous high humidity are added to the previous 12 hours to total 24.
