data table will update at its own data table interval or according to a trigger set
within the program.
The data file consists of five or more rows. Each row consists of columns, or
fields. The first four rows constitute the file header. Subsequent rows contain
data records.

Each data table is associated with overhead information, referred to as “table
definitions,” that becomes part of the file header (first few lines of the file)
when data are downloaded to a PC.
The first header row of the data table is the environment line. It consists of
eight fields, listed in TABLE 5-3 .

The second header row reports fieldnames. This row consists of fieldnames
that identify the name of individual fields as given in the datalogger program.
Default fieldnames are a combination of the variable names (or aliases) from
which data are derived and a three-letter suffix. The suffix is an abbreviation of
the data process that outputs the data to storage. See TABLE 5-4 for a list of
these abbreviations.
