Hi abbasr,

i got an important problem when I want to get and monitor measurement data

Which problem do you get? Any error descriptions/numbers?

I recieved unclear data .

What are "unclear" data? Any more descriptions?

Generic answer after löooking at your image:

- Don't use VISA references with plain old GPIB functions. They expect other "address strings" - read the LabVIEW help!

- Always do double checks when you see coercion dots in your VIs: they are there for a reason and they have consequences!

- Always do some error checking - even those old GPIB functions have error IO!

Hi GerdW

Thanks for your attention and guide

Excuse me for delay in reply

I corrected the program as you said but I didn't saw any change in recieved data .

I attached recieved data again please open text file and saw .

I think this data must be converted to clear data but I don't know how can I convert it ?

What do you think about this problem ?

Please help me .

Best Regards.

HI abbas,

you need to know the content of that data file!

Once you know which information is stored and once you know how this information is stored (which format) you can easily decode this data.txt file. As I don't want to read the manual of your DAQ device nor do I know which settings you used you will have to do this on your own!
