Exercise 1 – Using a Computer based Light Intensity Data logger

Objective

To learn how to use a computer based measurement system

Over the next few exercises, you will learn how to use LabVIEW, the Low Cost Data Acquisition Training kit with a Photodiode to build a Light Intensity Logging System. In this exercise, we will run the final resulting logger called the Light System Demo VI so that you have an idea what we intend to achieve.

  1. The DAQ Training Kit comprising the EMANT300 USB DAQ module, Light Application Adaptor and the USB cable should already been connected to your PC. LabVIEW and NI-VISA library should also been installed. If not, STOP and read Appendix A for setup before proceeding with the rest of the exercises.

Convention Note:

All files names are in courier new font Light System Demo.vi

You should have 3 folders.

  • Learn DAQ and LabVIEW folder – contains the solution VI to all the exercises

  • Driver & Example VI folder – contains the EMANT300 driver

  • Working VI folder – storing the programs that you will create over the next few exercises.

  1. Click on the LabVIEW icon on your desktop to launch LabVIEW. You should see the following splash screen.
