Sometimes delay observed when measuring preassure and air flow by Meilhaus Card

[nparyan]

Hi everyone,

I'm an engineer working on pneumatic systems in Germany. I have a program (.exe file) generated by LabWindows which I use to measure the pressure and flow of air through a valve. The programm is most of the time reliable, but sometimes (although very seldom) the measurement is not real time, i.e., the read in sensor value is several seconds delayed. I've been working with the software for 7 months now and this problem occurred only two times. The problem is that we're working on products and the measurement must always be real time. Could anyone suggest why such thing occurs?

Thanks much!!
