需要注意的是，在循环模式下，当数据日志填充可用内存时，日志将围绕内存结构的第一个可用寄存器，指向第一记录第一项的日志指针将随日志中的每个附加条目一起随时间浮动。例如，如果数据日志多次环绕可用内存，则指向第一条记录的第一项的日志指针在内存中始终以指向最后一条记录之后的第一项记录的日志指针开头。当每个新条目写入日志时，这两个指针向下移动到内存中的下一个记录空间，覆盖当前日志时间和日期时日志中的第一个条目。下面列出的数据日志参数是可用于通过数据记录器捕获数据的参数。请注意，这些参数将按照此表中显示的顺序和大小放置在数据日志的记录结构中。
It is important to note that when in the Circulate mode, and the Data Log fills the available memory, the Log wraps around the first available Register of the memory structure and the Log Pointer to First Item of First Record will float along in time with each additional entry into the Log. For example, if the Data Log has wrapped around the available memory more than once, the Log Pointer to First Item of First Record will always be preceded in memory by the Log Pointer to First Item of Record After Last. As each new entry is written into the Log, these two pointers move down to the next record space in memory, overwriting the first entry into the log as of the Present Log Time and Date.Data Log Parameters Listed below are the parameters available for capturing data via the Data Logger. Note that these parameters will be placed within the Record structure of the Data Log in the order and size that they appear in this table.
