4.5 About data tables
A data table is essentially a file that resides in datalogger memory (for information on data table
storage, see
Data memory (p. 38)). The 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. Data tables may store individual measurements, individual calculated values, or summary
data such as averages, maximums, or minimums.
Typically, files are written to based on time or event. The number of data tables is limited to 250.
You can retrieve data based on a schedule or by manually choosing to collect data using
datalogger support software (see
Collecting data (p. 29)).
