The third header line identifies engineering units for that field of data. These
units are declared at the beginning of a CRBasic program, as shown in CRBasic
example Definition and Use of a Data Table
(p. 132). Units are strictly for
documentation. The CR3000 does not make use of declared units, nor does it
check their accuracy.
The fourth line of the header reports the data process used to produce the field of
data, e.g., avg (average), his (historgram), etc.
Subsequent lines are observed data and associated record keeping. The first field
being a time stamp, the second the record (data line) number.
Read More! See table Abbreviations of Names of Data Processes
(p. 153) for a list
of default field names.
As shown in CRBasic example Definition and Use of a Data Table (p. 132), data
table declaration begins with the DataTable() instruction and ends with the
EndTable() instruction. Between DataTable() and EndTable() are instructions
that define what data to store and under what conditions data are stored. A data
table must be called by the CRBasic program for data storage processing to occur.
Typically, data tables are called by the CallTable() instruction once each Scan.
