Time Stamp Error

[PleaseHelpWithLabView]

Hi,

My overall VI goal is to read a voltage difference, convert this to a pressure measurement, then output this information to a file with a timestamp (reading once per second).

The problem is that after the first 10 seconds, the time stamp continually resets to Jan.1.1904 - 0:00:00.00

It continues to reset every 10 seconds, please help!

Well, you are using the Dreaded DAQ Assistant (DDA, for short), meant for people who don't know (and don't want to learn) LabVIEW.  TimeStamps are a special type in LabVIEW, and represent the number of seconds (to a very high precision) since 1 Jan 1904.  Your DAQ Assistants are acquiring 10 points at 1 Hz.  If you repeatedly generate 10 points and plot them, letting the X values repeat from 0 to 9 (or 1 to 10), and represent these numbers (0 to 10) as LabVIEW TimeStamps, they will evaluate to 1 Jan 1904, 00:00:00.0 to 00:00:01.0.

I recommend learning enough LabVIEW (a few weeks should do it) to be able to not use the DDA and use real DAQmx functions.
