Hello Paul,
Can you give some further explanation into the trouble you are having? What DAQ device are you using? What voltage source are you measuring? Are you reading data from the Test Panels in Measurement & Automation Explorer (MAX) or from within LabVIEW or another programming environment? Can you elaborate some more on what you said about the "
start of every buffer the data goes to zero before equalizing at a constant value in a static situation".It sounds like you are talking about a continuous buffered acquisition. In this type of acquisition, the device begins gathering data from the specified analog input channel(s) into a buffer in memory when you call the DAQmx Start Task function. You then pull data out of the buffer into your application environment when you call the DAQmx Read function.
Let us know,
