Use Acquisition Mode as continuous ( with a while loop) and programatically incorporate a timer condition ( using Timing functions) to stop the acquisition ( the while loop) after 5 hours.
if I am sampling at high rate(1000 Hz)? What about the samples to read?
You should have no problem by setting Samples to read also as 1000, for continuous acq.
By doing so, You will get 1000 samples/sec of data for each of your channels
But one thing of concern: If you are saving the acquired data to a file, It will be a huge data file.
Think of how you would like to handle file saving ( I would suggest you save data in Binary format)
