AcuRite products track a variety of high and low records, including daily records, 48-hour records, monthly records, yearly 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, wind speed, and more.

Daily High and Low Records:

If your unit has a clock on it:

• The daily high and low records will be the maximum and minimum data recorded since midnight. These records will clear every day at midnight.

If your unit does not have a clock on it:

• The daily high and low records automatically clear every 24 hours. The time records are cleared is determined by the time the unit was powered on. For example, if the unit was powered on at 6:00 pm, then high/low records reset at 6:00 pm daily.

*Please check the specifications or manual to determine the features of a specific product.

Monthly High and Low Records:

Monthly high and low records are 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.

Yearly High and Low Records:

Yearly high and low records are the maximum/minimum data recorded throughout the calendar year, beginning on the 1st day of January and clearing at midnight on the last day of December.

All-time High and Low Records:

All-time high and low records are the maximum/minimum data recorded since the unit was first powered on, since batteries were installed, or the unit was last reset.

If the unit is the 00986 AcuRite Digital Fridge/Freezer Thermometer: 

• The min/max records appear to the right of the current temperature reading from each sensor. These readings reflect the minimum and maximum temperatures recorded since the batteries were inserted or since the CLR button was last pressed. To clear the min/max records, press and release the CLR button once. This clears the records from both sensors.
