The actual equipment of the Lab-Volt Pneumatics Training System is replaced with three-dimensional images, which students can manipulate on the computer screen. Using the mouse, students can install virtual pneumatic equipment in the laboratory, interconnect the equipment, perform a lab exercise, and obtain the same results as with the actual Lab-Volt training equipment.<br /> <br /> Sophisticated mathematical models fully simulate the mechanical and electrical characteristics of the pneumatic components (valves, cylinders, motor, flowmeter, and others) and electrical control devices (switches, relays, pilot lamps, etc.) in the actual Lab-Volt Pneumatics Training System. All components and devices contained in the LVSIM-PNEU software feature the same functionality and appearance as the actual equipment. Detailed cutaway views can be displayed to observe fluid flow inside the pneumatics components.";
