Multi function meter using VI
Virtual instrumentation is a new concept that has changed the way engineers and scientists approach measurement and automation. VI means measurement without physical devices.
VI is brought through easy-to-integrate software, such as the NI LabVIEW graphical development environment, and modular hardware, such as PCI modules. It is widely used for data acquisition and instrument control. VIs are viewable but not touchable i.e. no physical existence but performance is like a real instrument. It makes the computer and hardware to work for our wish.
