Multifunction DAQ
Samples Acquired
Hello adarshn,
Your stop loop terminal is wired to the "time elapsed" VI and with the values provided, you only run 100 cycles of 20ms (= 2 sec). If you acquire 1000 samples at 1kHz, measurement happens every second, therefore you go through only 3 cycles (2 before the time is elapsed, 1 after the stop is turned to true and the loop is effectively stoped) 😉
By the way, why would you use a Value node when your

Oops, seems like I missed some words 😛
What I wanted to say is that you don't need to use any property node as your boolean value could be read directly as an output of the for loop. Just wire it to the comparison VI ! Anyway, if your trigger the Elapsed Time VI with 0, your loop will just stop running. Do you want to stop your program whenever the acquired value is smaller than 0 ?
As for my recommandation to acquire more samples : the bigger is the number of cycles, the longer you will acquire data (if you want to stay at 1ksamples at 1kHz).
