CAPTURE ANALOG INPUT DROP

[alanled]

 I have 3 analog inputs which I continuously read and display the scaled results on 3 gauges (voltage converted to pressure 0v=0Bar 10v=300Bar) the final part of my test is to record the pressure drop of one of the analog input channels from 280Bar to 0Bar this should only take 70mS, and display this on a graph against time. Im struggling to find a way to capture this I have had a look ath the Daq examples but just dont seem to get this to work. Any help would be great.

What part does not work?  Data acquisition? Graph display? Detecting the drop in pressure?

Please post your code along with some typical data.

Hi

Check the below image. Might help to acquire data. I think you have to sample higher than 70msec for reading the channels.

Let me know if you have problem.

Thanks
