The Automatic DataAcquisition Unit is an interface box with software that connectsexperiments from the Structures range to a suitable computer. It allows datalogging, analysis and extra âvirtualâ simulated experiments. It accepts inputsfrom a digital force display, a digital strain display, an angular sensor anddigital deflection indicators. It converts these inputs into the correct datasignals for the computer. The software can then analyse the data and createtables and charts. The software can also simulate experiments which studentscan perform using the hardware, so they can compare simulated and real results.
