how to save 1 sample/minute

[nhan91213]

Hi.

I am using TDMS Write to save the data and the data saved right now is 10samples/minute.

What can I do to save only 1sample/minute or 1sample/5min?

Try wiring Time Elapsed Express VI into the Enable input to the Write to Measurement File function.

RavensFan,

TQ for the quick reply..

But I am currently using TDMS function.

How can I wire Time Elapsed Express VI to the TDMS Write function?

Wrap the TDMS Write with a Case structure and wire the Elapsed Time to that.

TQ jcarmody,

but where can I wire the Elapsed Time to the case structure?

Is it to the case selector or else?

Do you mean Elapsed Time or Time Elapsed Express VI?

Yes, wire the Time Elapsed? output of the Elapsed Time Express VI to the case selector of the Case structure.

Write to Measurement File does write to TDMS files.

Is sounds like you have an answer that works for you.  But I would recommend looking at the online LabVIEW tutorials
LabVIEW Introduction Course - Three Hours
LabVIEW Introduction Course - Six Hours

How case structures work is a very basic LabVIEW skill that would be covered in the tutorials.
