Hello
How to do AC Coupling in the LabVIEW code for acquiring acceleration from an IEPE accelerometer using NI 9232 and NI CompactDAQ system?

HI,
A quick google search for 'LabVIEW AC Coupling' yields this KnowledgeBase article, which explains how to use property nodes to select AC coupling in LabVEW: http://digital.ni.com/public.nsf/allkb/0B9BB4D7696CDA9F86256FA30063ECFC

Thank you so much for your reply. However, this leads me to another related question: The code I am attaching creates a channel for measuring pressure followed by a channel for measuring acceleration. If I put the property node for AC Coupling after the acceleration channel, is that gonna perform the coupling for the acceleration channel and skips the pressure channel. Actually I just want the coupling for the acceleration channel and to skip the pressure channel. another question: do I have to put the property node before or after the Timing VI. A shot of part of my code is attached.
regards

HI,
You can use the Active Channels (If Subset) property to first specify which physical channels to use AC coupling with. As far as positioning, It does not matter if it is before or after the timing VI.
