Ok, you have two data dependency issues with your local variables.  IE they are being READ before they are set in your adjust case.  I have fixed that (I think, as i can not run this VI).  I also made several changes to improve readability and resource management.  I believe I commented all changes.
The zip file contains only the serial read VI and a new typedef.  please look it over, and let me know if it fixes your problem and or if you have any questions.

Hi Mr Paul, Thank you very much for the advice.It help me a lot. I need some more advice from you again. For the minimum data read (initial before adjusting), may I know how to make it not to change during adjusting data,i.e not to change during adjusting, as a target spec. The user needs to do adjustment on the UUT according to the initial minimum data read. For the serial read, you have better and efficient way of doing it, may I know how? Thank you in advance for the help once again! Best Regards, Norman
