This text should make it easy to build custom systems for data acquisition, instruments control, data analysis, and data presentation. It offers a programming methodology in which users graphically assemble software modules called Virtual Instruments (VIs). LabVIEW can be used in a variety of industries and applications including: simulating heart functions, controlling an ice-cream making process, detecting hydrogen gas leaks on the space shuttle, modelling power systems to analyze power quality, and testing electronic circuit boards in computer and electronic devices.
