Need help with a VI to continuously read a voltage while a test operator manually adjusts potentiometer for calibration.

Hi,

I am trying to create a TestStand sequence where an operator must adjust a potentiometer on a PCBA while reading a voltage output from the board for purposes of calibration. How should I go about creating a LabView VI to accomplish this? I would like it to perform as follows:

-TestStand calls VI

-Pop-up gives instruction to adjust potentiometer until the monitored voltage is within tolerance

-Pop-up should show continuous voltage reading from the DMM within my DAQ

-Once within tolerance the operator can click ok to proceed running the rest of the TestStand sequence

I appreciate any guidance. 

Thanks!

Just create a VI with a while loop in which the stop condition is the OK button, and enable Show Front Panel When Called (See Keep LabVIEW Front Panel Displaying Continuously When Running TestStand). TestStand will wait until the VI is done executing before proceeding to the next step.
