NI ADEs have toolsthat allow you to easily save the data to files such as spread sheets for easyviewing, ASCII files for universality, or binary files for smaller file sizes.Completing the ApplicationAfter you have completed the measurement, analysis, and presentation ofthe data, it is important to stop and clear the task. This releases any memoryused by the task and frees up the DAQ hardware for use in another task.Note In LabVIEW, tasks are automatically cleared.Developing an Application Using LabVIEWThis section describes in more detail the steps shown in the typical programflowchart in Figure 5-1, such as how to create a task in LabVIEW andconfigure the channels of the SCXI-1503.
