Calculating the Total Days of Storage Available
This section includes a special equation to use in determining the
number of days of data that can be stored in the monitor memory
based on a specific application. Consider the following when
calculating the total days:
• The monitor memory holds 832 kilobytes (or 851,968 bytes) of
data.
• The log rate determines the number of readings taken per day.
At a 15-minute sample rate, the monitor will record 96 readings
a day for a single entity. At a 5-minute sample rate, the
monitor will record 288 readings a day for a single entity.
• One entity reading consumes 8 bytes of monitor memory.
• The following table lists the standard number of entities
recorded for each sensor device. The date/time stamp for a
reading is equal to one reading. Therefore, each total below
