Data Process Abbreviations - Campbell CR300 Series Operator's Manual

If a field is an element of an array, the fieldname will be followed by a list of
subscripts within parentheses that identifies the array index. For example, a
variable named Values, which is declared as a two-by-two array in the
datalogger program, will be represented by four fieldnames: Values(1,1),
Values(1,2), Values(2,1), and Values(2,2). Scalar variables will not have array
subscripts. There will be one value on this line for each scalar value defined by
the table.
If the default fieldnames are not acceptable to the programmer, FieldNames()
instruction can be used in the CRBasic program to customize the names.
TIMESTAMP, RECORD, BattV_Avg, PTemp_C_Avg, and Temp_C_Avg
are the default field names in TABLE 5-2, Typical Data Table
The third header row identifies engineering units for that field of data. These
units are declared at the beginning of a CRBasic program, as shown in
CRBasic Example B-6, Definition and Use of a Data Table
Cut, units are chosen when sensors or measurements are added. Units are
strictly for documentation. The CR300 does not make use of declared units, nor
does it check their accuracy.
The fourth header row reports abbreviations of the data process used to
produce the field of data. See TABLE 5-4.
