usb 6009 acquisition fall after 15min

[skling]

Hello,

Like it's said on the name of my post i have some problem with my new usb 6009. When i start it all work good but after a while my two AI fall to 0V. I put my code in joint pieces. I use AI0 and AI1 with a 220ohm resistance.

Thank you

Hi skling,

DON'T use an additional Wait function when you have set your DAQmxRead to use a certain sample rate!

It will wait on it's own and after some time you will miss to read samples in time...
