PSU and DMM tunning loop

$

Hi All,

 

I am attempting to setup a vi to control the output of a PSU using a DMM. Within my application I want to be able to precisely set a Voltage to within 10mV. This will come in handy when I am not able to directly measure the output of the PSU.

 

I am sure this has been done a thousand times before but I cannot find any examples.

 

I have attached my example circuit so far and would like to know if I am on the right track or maybe there is a better way to do this task? The code is only a rough outline and does not contain the VI to setup the PSU or DMM as yet.

 

When I debug the code it seems to run as intended but I have not considered any fault conditions or put safety limits in place.

Thanks for any comments
