As you will most likely notice, there are empty array elements in the output array on the Front Panel of this VI. See the previous array. There are very fundamental reasons I have left the VI as is (that is, if the purpose of the VI is to collect voltages, obviously we are not interested in blank array elements). Fundamental to data acquisition is verification of the data acquired in clearly defined milestones. Here we use "milestone" in the broadest sense of the word. A milestone may be the values a SUB VI is programmed to do or how a complete product is designed to function. Usually, a product is the end result of the labor of different teams of engineers working in collaboration. What may be considered the end of a working product (or part of a product) for a team of developers often is not where the collaborating team may be able to directly start to resume further development. A temperature sensor may send actual temperature values in string form, then again many...

Overview of this book
NI LabVIEW's intuitive graphical interface eliminates the steep learning curve associated with text-based languages such as C or C++. LabVIEW is a proven and powerful integrated development environment to interact with measurement and control hardware, analyze data, publish results, and distribute systems.
This hands-on tutorial guide helps you harness the power of LabVIEW for data acquisition. This book begins with a quick introduction to LabVIEW, running through the fundamentals of communication and data collection. Then get to grips with the auto-code generation feature of LabVIEW using its GUI interface. You will learn how to use NI-DAQmax Data acquisition VIs, showing how LabVIEW can be used to appropriate a true physical phenomenon (such as temperature, light, and so on) and convert it to an appropriate data type that can be manipulated and analyzed with a computer. You will also learn how to create Distribution Kit for LabVIEW, acquainting yourself with various debugging techniques offered by LabVIEW to help you in situations where bugs are not letting you run your programs as intended.
By the end of the book, you will have a clear idea how to build your own data acquisition system independently and much more.
