Array to spreadsheet problem

[Oesen]

I have set the both values to 1, but still getting that problem. It gives 600+ measurement every second 😞

I don't think I believe that. When I set the sample rate and the number of samples to both 1, I get exactly 1 sample per second, just like it is supposed to.

[Oesen]

Thanks for the answer Dennis

I use NI-9237 as a DAQ device

I will try again now:

It still shows the same (many thousands samples per second) ! 😞

[Oesen]

There is exactly 6289 samples in 4 seconds of time

Where are you looking at and seeing all of those samples? I don't see them at the output of the DAQ Assistant. I don't have your hardware. Perhaps that device has a minimum number of samples. What does the spec say?

[Oesen]

Hi Dennis.

I read all those samplings in the .csv file i'm writing to.

If you look at the Sample time (timestamp) and run the VI, it acts like a second the first few second, but it will be more than a second the longer the VI runs.

Are you using a simluated device or you have a real DAQ card?. Did you try logging with the tdms data logging available with the DAQ assistant?

Did you check the loop rate?

I Use "Internal" as a Vex Source

Hi P@Anand

I use NI-9237 as a DAQ device.

I have enabled the TDMS logging, but still get the same result 😞

[P@Anand]

No after enabling the tdms data logging disable the file you are writing. You do not need that automatically the data will be saved in .tdms format, check the file shown in the tdms data logging configuration.
