Program
The program section defines the action of datalogging
Set scan interval The scan sets the interval for a series of measurements
Measurements Enter the measurements to make
Processing Enter any additional processing with the measurements
Call Data Table(s)
The Data Table must be called to process output data
Initiate controls Check measurements and Initiate controls if necessary
NextScan Loop back (and wait if necessary) for the next scan
End Program
