accuracy of wait(ms).vi

[whatsthis4]

If I insert a 100ms wait, what is the minimum error I can expect, +/-1ms? ie - 99-101ms wait?

What would be a common worst case scenario?

[Shiner]

That depends on the OS that you are using.
The best you can expect is 100ms, but the worst in theory is infinite.

[Jeremy Braden]

This is because Windows can always make the LabVIEW application wait while it does something else which in theory could make LabVIEW wait forever.

Hi Jeremy,

I saw lot of your postings related to setting priority of VI's and sub VI. I dint know how to get your e-mail address. So I have posted my question as a comment of this mail. This question is not related to the earlier posted question.

I am performing 2 time critical counter operations. I am using software time due to the hardware limitation of PCI6013(I have tried all other options). My problem is that I get a erractic value when I use mouse, keyboard or change to other application.


I found your following link providing a method to provide maximum priority to labview application.But you have asked even regular labview users not to use this application. I am not even a regular LABview user. Is there any precaution that
I should take to use this VI. I am in need of such an application very badly. Please Help.
