12.5.1.2 Data records

Subsequent rows are called data records. They include observed data and associated record
keeping. The first field is a time stamp (TS), and the second field is the record number (RN).
The time stamp shown represents the time at the beginning of the scan in which the data is
written. Therefore, in record number 3 in the previous
the average of the measurements taken over the minute beginning at 14:26:01 and ending at
14:27:00. As another example, consider rainfall measured every second with a daily total rainfall
recorded in a data table written at midnight. The record time stamped 2019-03-08 00:00:00 will
contain the total rainfall beginning at 2019-03-07 00:00:01 and ending at 2019-03-08 00:00:00.

12.6 Creating data tables in a program

Data is stored in tables as directed by the CRBasic program. In Short Cut, data tables are created
in the Output steps (see
created within the CRBasic data logger program using the
instructions. They are placed after variable declarations and before the

under what conditions data is stored. A data table must be called by the CRBasic program for
data processing and storage to occur. Typically, data tables are called by the
instruction once each Scan. These instructions include:
See the CRBasic Editor help for detailed instruction information and program examples:

Use the DataTable() instruction to define the number of records, or rows, allocated to a data
table. You can set a specific number of records, which is recommended for conditional tables, or
