String and Boolean variables can be output with the Sample() instruction. Results of
Sampling a Boolean variable will be either -1 or 0 in the collected Data Table. A Boolean
displays in the Numeric Monitor Public and Data Tables as true or false.
16.5 About data tables
A data table is essentially a file that resides in data logger memory (for information on data table
storage. See Data memory(p. 88). 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 20,
which includes the Public, Status, DataTableInfo, and ConstTable. You can retrieve data based on
a schedule or by manually choosing to collect data using data logger support software. See
Collecting data(p. 77).
