About this Application:
This application is designed to make measurements with an NI-9237 very easy and quick. It has the ability to scale the data being acquired on execution and provides flexibility with how you would like to achieve this scaling. The following picture shows the front panel for this application:
As can be seen from the above image the main settings that specify bridge type and excitation are found here. You can also select whether to perform offset nulling or shunt calibration. If you wish to set up a new scale you can simply press the “Calibrate?” button and hit run. This will open a new dialogue box like the one below:
This dialogue box allows for the comparison between electrical values and physical values which will log the new scale to file. There are 3 different scaling types:
Linear
Map Range
Table
The block diagram code for this scaling subVI consists of a large case structure which is selected by the tab control that allows you to see the different scale types. An example of some of the code can be seen in the block diagram picture below:
After the scaling settings have been applied the user is returned to the main front panel in which they will see their acquisition happening live in the graph. This data is logged to file for later use.
Operating Instructions:
In order to use this VI please follow the instructions as in these following steps:
10. When you are done with the experiment press the "Stop" button to close the application.

Is there a version of this that would write the log files to a spreadsheet? Thank you
