TEMPERATURE RUNNING AVERAGE WITH CONTROL TUTORIAL
![](../images/labview_0233.jpg)
INTRODUCTION
In this exercise, you will open and modify the Temperature Running Average VI you created in an earlier tutorial. You will add an Overtemp control that utilizes a Case Structure to indicate when the current temperature is above a value entered in a Digital Control on the Front Panel. When the current temperature goes over the value, a Boolean Indicator will light and a beeping sound will occur on the computer's speaker until the temperature goes below the upper temperature limit.
- Open the Temperature_Running_Average.vi you created in an earlier tutorial
- Save-As to Temperature_Running_Average_With_Control.vi
- Add and wire components as shown above
- Run the VI Continuously, change the Upper Limit value and observe the results
- Save the VI
