controlling of time delay in data aquisiting

[labmaster]

I want to control the time delay between aquisitions by DAQ.

like in my main_subroutine(acquiring and displaying) for continuous aquisition,

acquire data from DAQ -> delay -> acquire -> delay ....

The time interal was very irregular for 70 ms delay.

My data will be compared with a file-a file.

What is the best way to synchronize between each time steps? 

0.0000
0.0781
0.1406
0.2188
0.2813
0.3594
0.4219
0.5000
0.5625
0.6406
0.7188
0.7813
0.8594
0.9219
1.0000
1.0625
1.1406
1.2031
1.2813
1.3438
1.4219

I would suggest a timed loop. It is the best way.

Another option :

The time delay is not proper for setting the delay in your case. The "wait until next ms multiple" in your case is better. Check the Labview help, to see the difference.

Thanks Pnt,

The timed loop was more precise in using a delay function.
