LabVIEW programming is called virtual instruments, or Vis, because of their appearance and operation physical instrument, such as oscilloscopes and multimeters. LabVIEW Vis contain three components the Front panel, the block diagram, and the icon.In Labview, you build a user interface, or front panel, with controls and indicators. Controls are Knobs, push-button, and other input devices. Indicators are LED and other displays. After user interface, you add code using VIs to control the front panel objects. In the block diagram make the code. This technical manual introduces the concepts required to build a basic system with LabVIEW. We recommend that new users spend time learning the basic tools and concepts needed to use and navigate the environment before building their first applications
