DAQ Assist Rate

[MTGeotech]

Hello All,

I am looking to obtain a "useable" amount of data from my labview program. I am collecting data from the NI USB-6008 which has a sample rate of 10kS/s, Just using a simple VI using the DAQ Assistant I have it exporting the values into excel. The problem I am encountering is that with is I am having to much excel data to be able to actually use the information. I have tried to change the rate and samples to read in the DAQ to low numbers (1 sample to read at 2 Hz). But I am still getting a huge amount of data. In an Ideal world I would like to be getting about 1 data point every 2 seconds. 

Thanks!

Hi MTGeo,

then just read one datapoint each 2 seconds!

Change your DAQAssistent from "HW sample rate" to "on demand"…

When putting the sample rate to "On Deman" how can I set the time of when collect samples. Idealy I would like one sample every 2 seconds for a period of 10 hours.

Thanks

For something this trivial, a wait (ms) ore delay function can be used. The Elapsed Time function is also suitable.

[MTGeotech]

Can these function be used in conjuntion with DAQ assist and Excel exporting?

Hi MT,

why shouldn't you be able to "Wait" for a certain amount of time in conjunction with DAQAssistent and Excel?

[MTGeotech]

No clue, that's why I asked

It's the sort of question that takes less time to actually try than it does to type it out, post it, and wait for an answer.
