Disabling output of a power supply and enabling it

I need to contol the ouput of my power supply when my mulitmeter reaches a certain voltage or drops below it. My question is how do I connect the multimeter to the power supply so that the power supply will be on until the mulitmeter reaches X voltage then turns back on when it goes below X voltage.

 

My Equipment:

1.HP 34401A Multimeter

2.HP E3631A Power Supply

 

Here is a picture of the block diagram. The Multimeter is on the left and the power supply is on the right. I have also attached the file to this post.

What you are asking is not simply a matter of connecting the two together. You need to design an entire program to implement the functionality that you desire. What have you done to this point to learn about LV and/or programming in general?

Mike,

 

My expierence is very minimal. I am a college student and we have been given this assignment with little to no information. Our teacher said we have to use any resource availible to figure this out and we cant get passed this part.

 

(This project is supposed to read a voltage from a thermocouple then turn the solering iron on and off depending on that voltage to keep it at a certain temperature.)

Here is how I would start. You will need to do more to this but should give you an idea of how to get started. This was a very quick and dirty way of using what you had and making it do more.

 

You will need to set the limits on the in trange and you will have to hook the ture false back up to the set output.

I attempted to run the program and I had recieved a few errors. If you could please assist me in fixing them it would be much appreciated.

You will have to put this code in the same file that you had the old one in. Basicly it is telling you that it can not find the VI's that you used in the orginal code.

 

You will have to teach it where those files are or move it into the same file as your orginal code.
