High and Low Records
AcuRite products track a variety of high and low records, including daily records, 48-hour records, monthly records and all-time records. The High Record is the maximum reading recorded in the specified time period. The Low Record is the minimum reading recorded in the specified time period. High and low records are reported for temperature, humidity, high wind speed and more.
Please check the specifications or manual to determine the features of a specific product:
In general, if the product has a clock, the daily high and low records will be the maximum and minimum data recorded since midnight.
As a general rule of thumb, if the unit does not have a clock, the high and low records will clear every 24 hours. The time that records clear each day is determined by the time the battery was installed. For example, if the battery was installed at 6:00 pm, then records will reset at 6:00 pm daily.
Monthly high / low is the maximum / minimum data recorded throughout the calendar month, beginning on the 1st day of the month and clearing at midnight on the last day of the month.
All-time high / low is the maximum / minimum data recorded since the unit was first powered on or since batteries were installed.
