Labjack
First Project
This is my first project using the Labjack U12 Data Acquisition Device. Below is a very simple Labview program that reads the voltage of 2 AA batteries and writing the results to a file.
This all worked, one thing to note, that maybe noticeable in the pictures below is that when the batteries were disconnected, the result didn’t go to 0v. This is most likely due to the input being “floating”.

Second Project
This was based on the first project, but with a few updates.
- Resistor between A0 (Analouge In) and GND, to solve the floating issue
- Variable resistor to adjustthe voltage
As you can see from the pictures and video below, the project was a success, the voltage returned to 0 at the correct times , as well as a graph showing the different and varying voltage input.

Third Project
This project is quite an update based upon the previous projects, this project had the following updates.
- Second Analogue In with a variable resistor with a input voltage.
- Two data inputs plotted onto the same graph, in this case a 9v and 2AA voltage trace.
- A “math” function, where the 9V reading had the 2AA voltage reading subtracted from it, plotted on its own graph
- All three pieces of data saved to the same excel file.
Pictures and video show both the “front” and “back” end of the program, as well as the output data and how everything was wired.
